I have only slept one night this week, what do you think will happen if i keep this up.?

Well it is all because of midterms. I stayed up all of sunday and monday, untill about 3:00 AM Tuesday morning, then i slept until 3:45 PM tuesday afternoon, then a stayed up all of last night and still havent slept. I have gotten so much crap done this week i was wondering what would happen to me physically and mentally if I kept this routine up? sleeping well every other night instead of 4-6 hours every night? I will admit that the day would be tough with out my no-Doze. But I dont feel bad or anything. Maybe just a tad fatigued.
