@ShadenLines Have you read up on chronotypes? Seems some of us are just naturally inclined to sleep at later times, or even to need more or less sleep, from back when we were tribes. Unconventional times of waking may not be bad entirely, just a conflict with normalized work hours and environments...

_Errrgghh_...
These all-nighters will shorten my life, no doubt.
But what else can you do when there's just enough physical discomfort to keep you awake, but not enough to interfere with mental focus to an extent?... Nothing left except reading, & an occasional snack.
The only upside to this is it does contribute to being self-educated.
