How did this thing go? I disagree with the "get, plenty of sleep" posters. Staying awake is a marathon, and you don't train for a marathon by staying seated a lot. For me, and I had a crazed schedule, it was nearly impossible to pull 48-60 hour shifts if I was well rested. On the other hand, if I started getting three hours sleep a night for weeks on end, then two, then one, all- and multi-nighters weren't so tough to pull off.
