Yup... every time I oversleep I feel like I need 5 more hours...

My friend tried polyphasic once. He did it for a few weeks, at least. At the time I was pulling all-nighters a lot so I would stay up with him and play games. It was nice to have someone to do that with on weekdays. But with school, I'm unfortunately pretty stuck in the 9 to 5 type routine, so I wouldn't really be able to take twenty minute breaks at regular intervals like that. Maybe if I decided to go into something other than education.
