I think I found your answer here..
” although I was up for 34 hours before that “
Amazingly, I didn’t really feel tired for most of my 34 hours of being awake. However, after about 32 hours, it started to get hard to function. It was a really great experience. But it’s normal for me to sleep than long without an alarm, even if I was only awake for 18 or 19 hours that day. Sleep isn’t bad for you, but it kind of hurts your waking world life.
