I can't say I enjoyed it, but the most common one is definitely I had shit due the next day. I don't enjoy staying up past 24 hours, but some weeks that was absolutely necessary. If you find you have to stick to a set sleep schedule, then the sciences probably isn't for you unless you are freakishly proactive with assignments.
I'm also a bad sleeper, which doesn't help. Not insomnia, I just wake up a lot when I do sleep. On the plus side, that means sometimes I can wake fully rested with 3 hours of sleep (not terribly often, but when needed).
Longest I've done a gaming session is probably 16 hours, and that was pen and paper. Longest for computer is probably 10.
