Sleep quality is structure, not just hours: latency, deep‑sleep proportion (N3), and next‑day refreshment all matter.†
PM support works best when you also adjust light, temperature, and meal timing.†
Keep AM/PM signals separate so daytime arousal pathways stay in their lane.†
1) Sleep, unpacked
Sleep latency: From lights out to sleep onset; target <20–30 minutes.
Deep sleep (N3): Supports physical restoration and glymphatic clean‑up.
Morning refreshment: The subjective “feel” that tells you the night worked.
2) PM routine, step‑by‑step

3) Common issues & fixes
| Issue | Possible Causes | Adjustment Recommendations |
| Middle-of-the-night wakeups | Drinking too much water or alcohol before bed, overly high bedroom temperature; or delayed sleep schedule | Check and reduce evening fluid and alcohol intake, keep the bedroom at a comfortably low temperature; if you go to bed late, take the PM formula in advance to help relax† |
| Travel nights | Jet lag disrupting the circadian rhythm | Start taking the PM formula according to local time from day one to maintain a consistent schedule; use an eye mask and have a light breakfast the next morning to help adjust your rhythm |
| Caffeine spillover | Caffeine intake in the afternoon or evening causing nighttime alertness | Limit caffeine intake to before early afternoon; for those sensitive to caffeine, take the AM formula around breakfast time, and separate it from other ingredients by ≥60–90 minutes† |
4) Why split day vs night at all?
Because your body naturally alternates between daytime activity and nighttime recovery. A single “all‑day” blend risks muddling those signals.†
