staying awake for 2 days isn't going to make anything really bad happen. if he goes past that, maybe. but if he just goes for the 48 hours, he's fine.
Oh yeah, that's exactly my recollection of my experience, or what other students tried to warn me about during Major Project. 48 hours and then I got sleep and I was
totally fine. No problems, nuh-uh.
Look at the bunch of physicians on this site, guys! Full of accurate, up-to-date medical advice. I'm proud of you forgeters.
