Waking up at 10:15 PM
Alarms set for 10:15 PM cover the schedules nobody designs on purpose: jet lag that flips day and night, a nap before a night drive, a split-sleep experiment, or simply a body clock that runs on its own timetable.
The core rule survives any schedule — wake at the end of a cycle, not in the middle of one. From 10:15 PM, count back: asleep by 2:45 PM for five full cycles, or 1:15 PM for the whole nine hours. Consistency at strange hours still counts as consistency.
Keep the wake-up mechanics boring and reliable: volume high, phone out of arm’s reach, water beside the bed. At this hour a missed alarm has real consequences, so let the routine do the work — not your middle-of-the-night judgment.
