Sleep
Caffeine Cutoff Window
A caffeine cutoff window is the latest time you stop coffee, tea, or energy drinks so adenosine can rise and melatonin is not delayed—often six to eight hours before bed, though sensitivity varies. Afternoon espresso that feels fine at work can still fragment deep sleep you never notice until morning grogginess.

Track cutoff against latency and wake-after-sleep-onset, not vibes alone.
