I have remained more or less normally functional from 6:30 am to nearly 11 pm, managed to conquer an unusual amount of my to do list, with only my usual amount of caffeine Still got it Now SPLAT
Every once in a while, just to make sure I can still do it, I see if I still have the ability to function semi-normally on 3 hours of sleep, like the newborn days (Not really but that maybe sounds better than “I stayed up until nearly 3 am reading bc wtf is self-control”)
