What happens when you don't get any sleep at all?

The last time I didn't get enough sleep, very bad things happened, although it was combined with a lot of stress from Uni work and a lack of any breakfast for three consecutive days. You see, I had only been allowing myself about 4 hours per night for three night.

So there I was, in the computer lab walking to the laser printer to pick something up. The next second, I was sitting in a chair with people staring at me; apparently i'd had a fatigue-induced seizure and been flailing around on the floor. At first I thought nothing of it and tried ot get up but promptly fell back on my ass because I was so weak. I also had grazes on my head and wrists from the carpet as I was flailing.

Some nice guy there took me to the hospital, and they did a blood-test of some sort. They found nothing wrong so I just went home and had the rest of the day off. I didn't feel bad after a few hours, but I was worried at first that it might be some form of chronic epiliepsy, which would have effectively made me useless for anything in my life that involved machinery, driving, or crossing the street.

I also can't imagine what it must have looked like to my friends; it was so embarrassing.

Jam it back in, in the dark.
