If sleep is drifting, start with the clock and the bed. Most supplement stacks work poorly when wake time, light timing, caffeine, alcohol, and time awake in bed are working against you.
Sleep depends on two major forces: circadian timing and sleep pressure. Circadian timing is your internal clock. Sleep pressure is the drive that builds while you are awake. Poor sleep often happens when these two forces are misaligned, or when the bed becomes a place for worry, scrolling, and effort.
Use this guide as the reset plan. For a shorter checklist, see Sleep Starter Kit. For troubleshooting patterns, see Troubleshooting Poor Sleep.
| Intervention | Evidence | What to do | Notes |
|---|---|---|---|
| CBT-I | High for chronic insomnia | Use a trained provider, validated program, or structured self-help when insomnia is persistent. | AASM strongly recommends cognitive behavioral therapy for insomnia.[1] |
| Wake-time consistency | Moderate to high | Pick a wake time and protect it for one week before changing supplements. | Stable timing helps align circadian rhythm and sleep pressure.[2] |
| Stimulus control | Moderate to high | Bed is for sleep and intimacy. If awake too long, get up briefly. | AASM conditionally recommends stimulus control as a single component.[1:1] |
| Sleep restriction or sleep compression | Moderate | Reduce excess time in bed under guidance if insomnia is chronic. | This can be effective but uncomfortable; use caution with bipolar disorder, seizure risk, or safety-sensitive work.[1:2] |
| Supplements | Situation-specific | Use after timing and behavior are addressed. Keep doses conservative. | Melatonin is a clock-timing tool, not a general sedative for every sleep problem.[3] |
| Day | Action | Why |
|---|---|---|
| 1 | Choose a wake time and set it for all seven days. | Wake time anchors the clock. |
| 2 | Get outdoor light within one hour of waking. | Morning light strengthens daytime alertness and night timing. |
| 3 | Stop caffeine early enough that it is not active at bedtime. | Late caffeine can fragment sleep even when you fall asleep. |
| 4 | Dim lights and screens 1-2 hours before bed. | Evening light delays the clock for many people. |
| 5 | If awake more than 20-30 minutes, leave bed briefly. | This rebuilds the bed-sleep association. |
| 6 | Keep the bedroom cool, dark, and quiet. | Environment reduces unnecessary arousal. |
| 7 | Review the pattern, not one bad night. | Sleep responds to consistency. |
Get medical help for severe daytime sleepiness, falling asleep while driving, loud snoring with witnessed pauses, restless legs that prevent sleep, shift-work impairment, mania symptoms, depression with suicidal thoughts, or insomnia that lasts more than three months despite a structured plan.
Often no. Sleep hygiene helps, but chronic insomnia usually needs CBT-I components such as stimulus control, sleep restriction or compression, and cognitive work.
Not automatically. Melatonin is most useful when timing is the issue. Dose, timing, age, medication interactions, and next-day effects matter.
Do not compensate with a long sleep-in unless safety requires it. Protect the next wake time and rebuild pressure the next day.
Run Sleep Starter Kit for the simple checklist, then use Troubleshooting Poor Sleep if you need symptom-specific fixes.
