Haha, I have no problems at all staying up all night - it's the eventual crash and burn after doing it for several days straight that does me in
I never understood why my engineering lectures were usually scheduled at 8 am, but the exams were scheduled for 7 pm... both were annoying! Top effort on 7 exams in 6 days, though - that's brutal.
I started doing all nighters during my engineering honours thesis and it continued well into the PhD. On the bright side, it meant that I ran waaay too many experiments - my 9th thesis-related journal article was accepted for publication today. They didn't tell me at the time that I only needed three to graduate!
