I can stay up for a maximum of 24 hours. Never gone past that amount though. I have never felt sick before. My eyes hurt and my eye lids feel like lead weights. I heard meth can make you stay up for 3 days straight no problem, you should try it some time.

That's always what happens to me when I try to stay up. I feel sick and light headed. It sucks.
