Do you stay up all night a lot? What's the longest time you've stayed awake? How do you act when you're sleep-deprived?

I'm about at... 31 hours after pulling my second all-nighter at law school to finish up a paper. The first was about a year ago for the journal competition, but I only made it to 27 hours or so as I then crashed for several hours. But before that, I can't even remember. I know when I was pretty young I stayed up about two full days just for the hell of it. I have no idea how I did it then.

For some reason I am still feeling rather awake. It is probably the drugs caffeine, but that usually doesn't affect me. Perhaps I have ascended to a higher state of being that does not require sleep. Though I have noticed that for the past couple hours unless I try unusually hard to pay attention that I to some degree have lost the ability to censor myself. Also a few times I have started to type a word and when I'm finished it is a completely different, unrelated word with entirely different letters. My fingers are cheeky little bastards like that.
