Sometimes I purposely miss doses of my medication because I want to be up for an extended period of time. I started doing this when I was in grad school, and I always procrastinated so much that this was the only way to get all my homework done on time.
Finals week, I think my first semester.... I stayed up for about 80 hours straight. I had all day to finish my last paper, but I literally could not think. I was afraid to take my pills and go to bed, because I thought I wouldn't be able to get up in time to finish my paper on time. But I had no choice, because I couldn't think, so I was stuck. So I went to bed at like 11:00 AM, woke up at like 9:00 PM, finished my paper and turned it in like an hour to 30 minutes before the deadline. Yeah!
