Is it normal to have moments of euphoria when staying awake for over 20 hours?
I never really stayed awake for unusually long of my own volition before last year. My high school had absolutely no party scene and I found it easy enough to get away with only studying in the day. Now I'm in university, and I've had to stay up increasingly more to study.
Yesterday, I was up for 22 hours, and, in those last few hours, I had seemingly inexplicable bursts of intense euphoria. They lasted for about ten seconds each. I could still think clearly, I was just unrealistically, nonsensically f-cking elated. It was the second time I've had this; both times, I had been awake for over 20 hours.
At the time, I wasn't about to complain, but now I'm a little concerned. I've never used any drugs to keep myself awake apart from coffee, and I usually love sleep, so I can't explain this at all.
Has anyone else had this? Is it normal?
