I already knew that, for the past six or so months, I haven't been getting enough sleep. 20-25 hours a week just doesn't cut it. But I think it's actually physically affecting me now. I'm falling asleep almost every day in one or more of my classes, and it might be messing with my depth perception. In short, I have a strong feeling that I'm going to be in a wreck sometime soon. ...just a feeling.
