[quote="con Brio":80583]What's the longest you've gone without sleep? I've two tests on Friday which I am not ready for; however, I'm inspired by the Navy SEAL Hell Week to pull two consecutive all-nighters. ed:

If the SEALs can go a week without sleep under high stress, then why can't I? (Then again, I'm not a SEAL now am I?) sleeping:[/quote:80583]

don't do it,
48 hours of cramming and no sleep followed by 2 exams = a grade of C or lower on both exams.

remember this:
1. SEALs do get some sleep during hell week, just not a lot
2. SEALs mainly do training designed to force the body and will to the breaking point, they mainly lug around heavy things, run, and do pushups. They don't do technical things that require concentration, like shooting or using sensitive equipment during hell week.
An exam is rather more mentally straining than pushups and hauling around a rubber boat.
