Why Sleep Became Non-Negotiable for Me
I used to think productivity meant pushing through exhaustion. But over time, I noticed something: When I slept well, everything else worked better — my focus, my mood, my skin, even my creativity. Travel made this even more obvious. Between late dinners, early flights, and unfamiliar environments, my sleep quality would fluctuate dramatically. I needed something simple, consistent, and portable — a routine that worked no matter where I was. That's what led me to build a sleep system around two essentials: 🩹 Sleep Patch🫦 Mouth Tape
Sleep as a System: What Burnout After Fisker Inc. Taught Me About Recovery
I spent eight years at Fisker Inc. — from 2016 to 2024 — giving everything to building and scaling companies. After August 2024, I finally stopped. And that is when I understood what those eight years had quietly cost my body, and what was possible when I began to treat recovery with the same rigour I had applied to everything else. GF Dr. Geeta Gupta-FiskerCo-Founder, Checked Out Inc. · Ph.D. Biotechnology, University of Cambridge March 17, 2026 · 6 min read From 2016 to 2024, I gave everything to Fisker Inc. Co-founding it, serving as CFO and COO, architecting the SPAC IPO, taking the company public on the NYSE — and doing much of it while travelling every other week. Europe was a constant. Investor meetings, board engagements, operational trips across multiple countries — there were stretches where I barely had time to unpack before I was back at the airport, managing a nine-hour time difference that my body never fully adjusted to before the next trip erased whatever progress I'd made. Like most people who travel at that frequency across that kind of time difference, I had a solution: melatonin. It was on every nightstand, in every carry-on. I took it to fall asleep on planes, to reset on landing, to bridge the nine-hour gap between where my body thought it was and where I needed it to function. It worked, in the narrow sense that it got me across the threshold of sleep when I needed to. But looking back, it was the beginning of a pattern I didn't fully recognise until much later — a progressive reliance on an external hormone to do something my body was gradually losing the ability to do on its own. The body keeps score quietly, and it is patient. It will let you borrow against your reserves for a very long time before it collects. After August 2024, the bill came due. The Burnout That Changed Everything Burnout doesn't announce itself with a dramatic collapse. For me it arrived in the months following my departure — a slow recognition that I was tired in a way that sleep wasn't fixing, that my mind felt fogged in a way that caffeine couldn't clear, that the clarity and drive I had relied on for eight years felt strangely distant. I had the time, finally, to rest. But rest wasn't happening the way I needed it to. Part of what I had to untangle was the melatonin dependency I had built up over years of frequent European travel. When you take melatonin as routinely as I had — not occasionally for jet lag, but almost every other week as a mechanism for bridging a nine-hour time difference — you gradually suppress your body's own production. The pineal gland, detecting chronically elevated melatonin, dials back. Over years, you produce less of your own. The supplement that started as a pragmatic travel tool becomes increasingly necessary just to feel like sleep is possible at all. Years of taking melatonin every two weeks to bridge a nine-hour time difference had quietly suppressed my body's own production. The supplement that started as a travel tool had become a dependency I hadn't seen coming. This is the cruel paradox of post-high-performance burnout compounded by hormonal dependency: by the time you stop, your nervous system has forgotten how to downshift, and the biological machinery for producing your own sleep hormones has been quietly undermined. The sleep that should be restorative becomes fragmented. You lie awake when you finally have permission to sleep. You wake exhausted from nights that should have restored you. I started paying attention — not to quarterly figures or capital structures, but to the data of my own biology. What was actually happening physiologically? What was driving the 3am wakefulness, the shallow rest, the morning fog that persisted even after long nights? And what had eight years of bi-weekly transatlantic crossings and routine melatonin use actually cost my body's own chemistry? What Growing Up in India Had Already Taught Me Before any of the science, there was something I had carried from childhood without fully understanding it. Growing up in India, the answer to sleeplessness was never a pill. It was a ritual. A particular warm drink, a herb known for its calming properties, a specific sequence of winding down that the body came to recognise as permission to rest. Sleep was treated not as something that happened to you, but as something you prepared for — something you invited. During the post-Fisker period, I came back to this. I started reading the research behind what those traditional practices had understood intuitively — why certain herbs calm the nervous system, why ritual matters for circadian signalling, why the pharmaceutical shortcut of synthetic melatonin often produces a worse outcome than working with the body's own chemistry. And I realised that modern wellness had largely abandoned this wisdom in favour of convenience, and that the gap between what tradition understood and what most supplements deliver was enormous. That gap was the seed of Checked Out. From Recovery to Rebuilding The months following August 2024 gave me something I hadn't had in eight years: unstructured time. Time to think without urgency, to sleep without an alarm dictating the outcome, to pay attention to what my body was actually telling me rather than overriding it in service of the next deliverable. And the more I slept — properly, deeply, with intention — the more clearly I could think. The relationship between sleep quality and cognitive clarity isn't subtle once you've experienced the contrast. The version of me operating on restored sleep was measurably more creative, more emotionally regulated, more able to hold complexity without anxiety. It wasn't that I had softened. I had sharpened. I also began to identify the specific things that were disrupting my sleep at a physiological level. The cortisol dysregulation that years of sustained high pressure had left behind. The mouth breathing I hadn't known I was doing. The gap between lying down and actually entering restorative deep sleep. Each had a specific biological mechanism — and each had a solution that didn't require pharmaceutical intervention. This is where the product thinking for Checked Out began. Not as a business exercise, but as a personal one. I was building a sleep system for myself, rooted in the science I understood as a biotechnologist and informed by what I had remembered from growing up in India — where sleep was never something you medicated, but something you prepared for. Building a System, Not a Sleep Aid When I eventually started working on Checked Out Inc. formally, I was thinking about a specific person — and that person was largely me, a year earlier. The high-performer whose nervous system has been running in overdrive. Who has tried melatonin, CBD, magnesium capsules, and ambient noise machines, all with inconsistent results. Who falls asleep but doesn't feel restored. Who has forgotten, or never learned, what it feels like to wake up genuinely ready. What that person needs isn't another thing to take. They need a system. A set of inputs that works with the body's existing chemistry rather than overriding it, that requires minimal effort to sustain, and that compounds over time rather than building dependency. The Sleep Patch delivers the cofactors the body needs to produce its own melatonin: Mg Magnesium Chloride — to activate the synthesis enzymes and regulate cortisol B6 Vitamins B6 and B12 — to drive the tryptophan-to-serotonin-to-melatonin conversion pathway L-T L-Theanine — to quiet the neurological hyperactivity that keeps post-burnout nervous systems alert long after bedtime GA GABA — to engage the brain's own inhibitory systems EC Ecklonia Cava — to deepen the slow-wave stages where physical and cognitive recovery actually occur Transdermal delivery over eight hours means no spike, no trough, no grogginess. Just steady, sustained support that runs quietly while you sleep. The Mouth Tape Insight The Mouth Tape came from a different realisation — one I made during the period of paying close attention to my own sleep. I was mouth breathing at night without knowing it. The signs, once I knew what to look for, were obvious: morning dry mouth, a persistent sense of having slept without having rested, mild headache on waking. Nasal breathing produces nitric oxide, humidifies and filters air, and maintains lower airway resistance — all of which support deeper sleep stages. Mouth breathing bypasses all of this. But when I looked at the mouth tape market, every product was purely functional — adhesive tape that keeps your mouth closed and nothing more. That felt like a missed opportunity. If something is on your face for eight hours during the peak cellular repair window, why shouldn't it be actively doing something for your skin? We built a mouth tape using medical-grade hydrocolloid infused with a peptide complex and hyaluronic acid. It supports nasal breathing and repairs your lips overnight. Two jobs. One product. Zero extra steps. Every hour of sleep is an hour your body is working. The question is whether you've given it the right conditions — and the right tools. Recovery Is Not the Opposite of Ambition The thing I most want people to take from my experience — and from Checked Out — is this: prioritising recovery is not a retreat from ambition. It is what makes sustained ambition possible. The version of me that emerged from that post-Fisker recovery period was not less driven. She was more effective. Clearer. More creative. Better able to hold complexity, manage relationships, and make decisions that I'm proud of in retrospect. The sleep hadn't softened the edge. It had sharpened it. I am building Checked Out with that understanding at its centre. Not as a wellness brand in the passive, decorative sense. As a performance tool. As a recovery system for people who take their output seriously enough to also take their input seriously. Why This Matters Now We are living in a moment of extraordinary complexity. The pace of change, the compression of decision cycles, the always-on nature of modern professional life — all of it places unprecedented demands on the human nervous system. The people navigating this most successfully will not be the ones who sleep the least. They will be the ones who have learned to recover most effectively. I learned that lesson the hard way — through exhaustion, burnout, and the long, quiet work of rebuilding. I am grateful for it. And I built Checked Out so that others might learn it a different way: not through depletion, but by design. Dr. Geeta Gupta-Fisker Co-Founder, Checked Out Inc.

Why Mouth Taping Is Everywhere — and What It Actually Does for Sleep
Not all mouth tape is created equal. Effectiveness depends on how it's designed, what it's made from, and how it feels on skin overnight. Mouth taping has become one of the most talked-about sleep wellness habits — but not all mouth tape is created equal. The effectiveness of mouth taping depends not just on the habit itself, but on how the tape is designed, what it's made from, and how it feels on skin overnight. Why Nasal Breathing Matters During Sleep Your nose is designed to do more than move air. Nasal breathing helps: Filter and humidify incoming air before it reaches your lungs Regulate airflow and maintain lower airway resistance Support calmer, deeper breathing patterns throughout the night Research shows that mouth breathing during sleep may be associated with dry mouth, disrupted sleep, and increased snoring. Your nose exists for a reason — overnight is when it matters most.

Sleep Patches Explained: How Topical Nighttime Support Fits Into a Better Routine
Not everyone wants pills, powders, or complicated nighttime supplements. That’s where topical sleep patches come in—designed to support nighttime routines passively while you sleep. But how do they work, and what should you look for? What Is a Sleep Patch? A sleep patch is a topical wellness patch applied to the skin before bed and worn overnight. Unlike ingestible supplements, patches work externally and are designed to be simple, consistent, and low-effort. They fit best into routines that prioritize calm, consistency, and minimal stimulation. Ingredient Philosophy: Why Simplicity Matters Checked Out Sleep Patch focuses on topical delivery and routine support, not overstimulation. While exact formulations vary, sleep patches commonly use ingredients associated with nighttime routines, such as: Calming botanical extracts Magnesium-adjacent compounds Melatonin-free formulations (important for some users) External education sources: NIH – Sleep Health & Supplements Sleep Foundation – Sleep Supplements Overview The Sleep Patch is not a medical treatment or sleep aid. Why Topical Support Appeals to Many People People choose sleep patches because they are: Non-ingestible Easy to use Travel-friendly Habit-supportive rather than habit-replacing They remove friction from nighttime routines. What Makes Checked Out Different Checked Out focuses on routine compatibility, not bold promises. Designed for overnight wear Minimal, mess-free application No pills or powders Works quietly in the background It’s meant to support sleep habits—not override them. Who It’s Best For People who dislike ingestible sleep products Travelers crossing time zones Anyone simplifying their nighttime routine Those stacking small habits for better sleep The best sleep tools are the ones you’ll actually use. Sleep patches work best when they’re simple, comfortable, and consistent—exactly how Checked Out designed them.Download this Blog
Why Melatonin Supplements Are Making Your Sleep Worse — Not Better
Melatonin is everywhere. Gummies, capsules, sprays, patches, chocolates. It's sold in airports, stacked next to vitamins in pharmacies, and recommended by well-meaning friends as the obvious first step when you can't sleep. It's so ubiquitous that most people assume it must be safe, effective, and broadly appropriate. It isn't — at least not in the way most people use it. The science on synthetic melatonin supplementation has become increasingly nuanced, and what's emerging paints a picture that the industry has been slow to acknowledge: taking melatonin regularly can actually degrade the very sleep system it's meant to support. What Melatonin Actually Does Melatonin is a hormone produced by the pineal gland in the brain. Its job is simple but critical: it signals to the body that it's dark, and therefore time to prepare for sleep. It doesn't cause sleep directly. It shifts the timing of your circadian clock — the internal 24-hour system that governs virtually every biological process. Under normal conditions, melatonin production begins rising about two hours before your natural sleep window, peaks in the middle of the night, and falls sharply before dawn. The whole cycle is orchestrated with precision. Light exposure, meal timing, temperature, and physical activity all feed into it. What a melatonin supplement does is introduce an external dose of this signal — which sounds helpful, but creates a problem most people don't anticipate. The core issue: Your pineal gland is sensitive to circulating melatonin levels. When it detects elevated melatonin from an external source, it reduces its own output. Over time, with regular supplementation, your endogenous production can diminish — making you more dependent on the supplement to feel sleepy at all. The Dose Problem Most melatonin supplements on the market are dramatically overdosed. Standard products contain 5mg, 10mg, even 20mg of melatonin. Research consistently shows that the effective physiological dose — the amount your body actually needs to shift its clock — is between 0.1mg and 0.5mg. 0.3mgEffective physiological dose 10mgTypical supplement dose 33×The overdose multiplier At 10mg, you're not gently nudging your circadian clock. You're flooding your system with a hormone at levels it was never designed to handle. The result is the next-morning grogginess that so many melatonin users know well — a kind of hormonal hangover as elevated melatonin continues circulating well past dawn. This isn't a minor inconvenience. Residual melatonin suppresses alertness, impairs cognition, and can affect mood throughout the following day. For people who take it nightly, the cumulative effect compounds. What Happens Over Time The body's response to any exogenous hormone follows a predictable pattern: downregulation. When you consistently introduce a substance that your body produces naturally, it adjusts its own production downward to compensate. This is the same mechanism behind steroid dependency, thyroid medication adjustments, and insulin sensitivity changes. With melatonin, regular supplementation has been associated with: Reduced pineal gland output — your brain makes less of its own melatonin Receptor desensitisation — your cells become less responsive to melatonin signals overall Circadian disruption — poorly timed doses can shift your sleep window in the wrong direction Hormonal crosstalk — melatonin interacts with reproductive hormones, cortisol, and insulin pathways in ways that are still being studied None of this means melatonin is dangerous for everyone, in all circumstances. For jet lag, shift work, or specific circadian rhythm disorders, small doses used briefly can be clinically appropriate. But as a nightly sleep aid taken indefinitely at high doses by otherwise healthy people? The risk-benefit calculation looks very different. The Grogginess Isn't a Side Effect — It's a Signal Morning grogginess after melatonin is widely dismissed as a minor inconvenience. But it's actually telling you something important: the dose was too high, the timing was off, or your body is struggling to clear it before morning. A hormone that's still biologically active at 7am was never supposed to be there. Your cortisol awakening response — the natural hormone surge that signals morning alertness — is blunted by circulating melatonin. The result isn't just grogginess. It's a dysregulated morning, a disrupted hormonal cascade, and a body that's confused about what time it actually is. People often take more melatonin to compensate for poor sleep quality — not realising that the melatonin itself is contributing to it. It becomes a loop: supplement → groggy morning → worse sleep → more supplement. What Works Instead The goal of any sleep intervention should be to support the body's own systems — not override them. Your pineal gland is capable of producing exactly the right amount of melatonin at exactly the right time. The question is whether the conditions exist for it to do so. Several compounds support melatonin synthesis and sleep quality without introducing exogenous hormones: L-Tryptophan → Serotonin → Melatonin This is the endogenous pathway your brain uses to make melatonin. L-Tryptophan is an amino acid that converts to 5-HTP, then to serotonin, then to melatonin. Supporting this pathway gives your body the raw material to produce melatonin on its own schedule, in its own dose. Magnesium Magnesium activates GABA receptors — the brain's primary inhibitory neurotransmitter — and is directly involved in regulating the nervous system for sleep. Deficiency is extraordinarily common and is one of the most overlooked drivers of poor sleep onset. L-Theanine An amino acid found in green tea, L-Theanine promotes alpha wave activity in the brain — the relaxed-but-alert state associated with the transition into sleep. It works without sedation and without the dependency risk of anything that acts on GABA directly. GABA Gamma-aminobutyric acid is the main inhibitory neurotransmitter in the central nervous system. Topical delivery (via transdermal patch) bypasses the blood-brain barrier limitations that make oral GABA supplementation less effective, making it a particularly relevant delivery mechanism for sleep support. Ecklonia Cava A marine algae with well-documented anxiolytic and sleep-architecture effects. Studies have shown it improves both sleep onset and time spent in deep sleep — without sedation and without hormonal interference. The Melatonin-Free Case At Checked Out, we made a deliberate decision from day one: no melatonin, ever. Not because melatonin is always inappropriate — but because the way it's sold and used in the modern wellness market actively undermines the biology it claims to support. High doses, nightly use, no titration, no medical oversight — it's a recipe for dependency and diminishing returns. Our Sleep Patch contains the full cofactor stack your body needs to produce and use its own melatonin effectively: L-Tryptophan, Magnesium Chloride, L-Theanine, GABA, Glycine, Ecklonia Cava, Vitamin B6, and Vitamin B12. Released transdermally across eight hours. No spike. No crash. No morning grogginess. The goal isn't to replace your sleep system. It's to give it everything it needs to work. That's what 0% melatonin actually means.
