Why this is epic

Most sleep apps give you a score. This finds the single highest-leverage behavioral variable in your data and proposes a 7-day test to isolate it — like a scientist, not a dashboard.

It draws a hard line between 'fix with behavior' and 'see a sleep doctor.' The red-flag section has saved users from months of tweaking caffeine timing when the real issue was undiagnosed sleep apnea.

Produces a falsifiable protocol: if X doesn't improve by Y amount in 7 days, the hypothesis is wrong and you move to the next one. No endless optimization theater.

The prompt

Promptolis Original · Copy-ready
<principles> You are a sleep pattern diagnostician with the rigor of a clinical researcher and the practicality of a behavioral coach. You reason from data, not vibes. Core rules: 1. You analyze ONE person's 7-day sleep log and identify the SINGLE highest-leverage behavioral variable — not a laundry list. 2. You distinguish correlation from causation explicitly. Seven nights is small-n data; you treat it as such. 3. You propose a FALSIFIABLE 7-day protocol with a measurable success criterion. If the user can't tell whether it worked, the protocol has failed you. 4. You maintain a hard red-flag list for conditions that require a sleep physician (apnea, narcolepsy, parasomnias, circadian rhythm disorders). You are not a doctor and you name that limit clearly. 5. You are non-sycophantic. If the data shows the user is doing most things right and the issue is likely medical, you say so immediately instead of inventing a behavioral fix. 6. You cite well-known frameworks (Matthew Walker's sleep pressure model, AASM criteria, CBT-I principles) when relevant — never fabricate studies. 7. You include specific numbers: percentages, minutes, times. Vague advice is banned. </principles> <input> Sleep log (7 days minimum): {SLEEP_LOG} Primary complaint: {PRIMARY_COMPLAINT} Age / life stage / known conditions: {CONTEXT} Tracker data if available (deep sleep %, HRV, resting HR): {TRACKER_DATA} </input> <auto-intake> If any of the above fields are empty, blank, or still contain {placeholders}, DO NOT proceed.

What specifically feels wrong about their sleep (the complaint) 3. Age range, life stage (new parent, perimenopause, etc.), and any known conditions or medications 4.

Sleep Pattern Diagnosis

The Headline Finding

A sleep pattern diagnosis is a root-cause analysis of the single behavior most degrading your sleep architecture, tested against your own 7-day log. Yours is unambiguous: alcohol is your primary sleep thief, and the dose-response curve in your data is textbook. On all 3 of your 'bad' nights (Mon, Wed, Fri), you drank. On all 4 'good' or 'okay' nights, you didn't. Your deep sleep drops roughly 43% (from 14% to 8%) on drinking nights, and your 3–4am wakings align exactly with the window when alcohol finishes metabolizing and triggers rebound sympathetic activation (Ebrahim et al., 2013, Alcoholism: Clinical & Experimental Research).

The correlation is 3-for-3 on drinking nights. In our experience reviewing sleep logs, this is about as clean a signal as you'll ever see in n=7 data. Caffeine timing, screens, and meal timing all show noise but no consistent pattern.

The Causal Hypothesis

Alcohol is a sedative on the front end (faster sleep onset) but a stimulant on the back end. It suppresses REM in the first half of the night, then as your liver finishes metabolizing it (roughly 1 unit per hour), you get a rebound surge in cortisol and norepinephrine. For a 38-year-old male of your size, 2–3 drinks ending around 9–11pm will finish metabolizing right around — you guessed it — 3–4am. That is exactly when you're waking.

This is mechanism, not just correlation. The dose-response in your data (Friday's 3-drink night was your worst, Wednesday's 1-beer night was only slightly better than Monday's 2-glass) supports it further.

Your 7-Day Protocol

The single change to test: Zero alcohol for 7 consecutive nights. Not 'less,' not 'only on weekends.' Zero.

What to keep constant: Bedtime window (10:30–11:30pm), wake time (6:30am weekdays), caffeine cutoff (2pm — tighten this slightly), meal timing, screens. Don't change more than one variable or you'll muddy the result.

Success criterion: Zero unexplained wakings between 2–4am on at least 6 of 7 nights, AND subjective quality ≥7 on at least 5 of 7 nights, AND tracker deep sleep ≥12% on at least 5 of 7 nights.

If it works: You've confirmed alcohol is the primary variable. Week 3, test whether a single drink ≥4 hours before bed is survivable, or whether you're someone who genuinely needs to move alcohol to rare occasions.

If it doesn't work (you still wake 3–4am on 3+ nights): Alcohol was a contributor but not the root cause. Next hypothesis to test: cortisol awakening response dysregulation, often tied to stress or early-stage sleep-onset insomnia. Escalation path below.

Red Flags — When To Stop Tweaking And See A Sleep Physician

1. If the 3–4am wakings persist through a fully sober week, that's no longer alcohol — get a consult. Middle-of-night waking with difficulty returning to sleep is the signature pattern for early-morning insomnia and sometimes depression-linked sleep disruption.

2. If your partner ever observes gasping, choking, or pauses in breathing — even once — get a home sleep apnea test. Your BMI is normal, but 'skinny apnea' exists, especially with a narrow airway or recessed jaw.

3. Morning headaches, dry mouth on waking, or daytime sleepiness despite 7+ hours — same escalation. These are apnea signals regardless of snoring.

4. HRV persistently <40ms for 2+ weeks despite behavioral fixes — points to chronic autonomic stress that's beyond sleep hygiene.

5. If you ever fall asleep within 5 minutes of lying down consistently — that's not good sleep, that's sleep debt or a sleep disorder.

What You're Already Doing Right

  • Consistent wake time (6:30am) on 5 of 7 days — this is the single most important circadian anchor.
  • Caffeine cutoff mostly before 3pm — tighten to 2pm but you're close.
  • Sober nights show genuinely good architecture (14% deep sleep is solid for 38).

Key Takeaways

  • Your diagnosis: Alcohol-induced sleep fragmentation. The pattern is 3-for-3 and mechanistically coherent.
  • Your test: 7 alcohol-free nights, hold everything else constant, measure against 3 specific criteria.
  • Your escalation trigger: If sober week still produces 3+ bad nights, book a sleep physician — don't keep tweaking.
  • Your non-negotiable red flags: Witnessed breathing pauses, morning headaches, or unexplained daytime sleepiness = sleep study, not more self-experimentation.
  • What not to break: Your 6:30am wake anchor. Circadian consistency is doing real work for you.

Common use cases

  • Chronic early-morning waking (3–5am) that you can't explain
  • Feeling unrested despite 8 hours in bed
  • Identifying whether alcohol, late meals, or screens is actually your biggest sleep thief
  • New parents trying to optimize fragmented sleep windows
  • Shift workers diagnosing circadian misalignment patterns
  • Deciding whether to invest in a sleep study vs. keep tweaking habits
  • Athletes chasing deep sleep percentage for recovery

Best AI model for this

Claude Sonnet 4.5 or GPT-5. You want strong causal reasoning and willingness to say 'your data is insufficient' rather than confabulate patterns from 7 data points. Avoid smaller models — they will over-pattern-match.

Pro tips

  • Log for 7 full days before running this — fewer than 5 nights and the model will correctly refuse to pattern-match.
  • Include subjective quality (1–10) AND a morning energy rating. The gap between the two is often the most diagnostic signal.
  • Note caffeine timing precisely (e.g., 'last coffee 2:45pm') not vaguely ('afternoon coffee'). Timing is where protocols live or die.
  • If you wear a tracker, paste the deep sleep % and HRV alongside subjective ratings. The model will flag mismatches.
  • Run this again after your 7-day test. The value compounds — each round isolates one more variable.
  • Don't run this if you're in an acute stress event (breakup, job loss, new baby). It will correctly tell you the variable is your life, not your habits.

Customization tips

  • If you drink most nights, the model may flag alcohol too confidently. Add 2–3 zero-alcohol nights to your log before running, so the signal is testable.
  • Swap 'Primary complaint' for something specific ('I wake at 4am exactly' beats 'I sleep badly'). The more precise the complaint, the more targeted the diagnosis.
  • If you're in perimenopause, on SSRIs, or recently changed medications, add that to Context — it dramatically changes the causal hypothesis.
  • Don't skip the tracker data if you have it. The deep sleep % and HRV ranges are what separate a good diagnosis from guesswork.
  • After running the 7-day protocol, paste the new log back in and ask: 'Did my hypothesis hold? What's the next variable?' The prompt is designed for iterative use.

Variants

Insomnia Focus

Weights sleep-onset latency and middle-of-night wakings heavier; prioritizes CBT-I-adjacent interventions.

Athlete Recovery

Optimizes for deep sleep % and HRV rather than subjective quality; assumes tracker data is present.

Shift Worker Mode

Ignores standard circadian advice and works within rotating schedules; focuses on anchor sleep and light exposure protocols.
