Build a Bedtime Routine
Find the earliest point the evening drifts. A routine starts before the user is already tired and bargaining with themselves.
Map the evening
Ask about usual sleep and wake times, target, work and care duties, meals, exercise, entertainment, devices, caffeine or alcohol context, environment, and where the plan normally breaks.
Screen for persistent insomnia, breathing pauses, dangerous daytime sleepiness, parasomnias, severe fatigue, mental-health symptoms, or other concerning symptoms. Recommend appropriate clinical evaluation rather than treating them as routine friction.
Choose one anchor
Pick the most stable event: work shutdown, kitchen close, alarm, device parking, shower, or first bedroom action. Attach the routine to that event, not a vague intention to “go to bed earlier.”
Reduce activation and friction
Build a short sequence the user does not hate. Prepare the environment before the anchor: needed items ready, avoidable light or noise reduced, and one high-friction choice removed.
Use WIND-DOWN-EXPERIMENT.md. Create a late-night version lasting five minutes or less so an imperfect evening does not erase the routine.
Review ease and adherence after seven nights. Change one element, not the whole system. Do not present the experiment as treatment for a sleep or mental-health condition and do not advise medication changes.
