PhoenixOwl: Yeah, it would be pretty hard to start polyphasic sleep during high school. The only way I can think of would be to do it temporarily during summer break, just to see what it's like. Don't know, just a thought.
andrew: It can be a lot of trouble to get started on it. I'm doing this mainly because 1) I look forward to the extra time in my day, 2) I'd like to see whether it increases my creativity (being a writer, I can use all the creativity I can get), and 3) I find it easier to experience lucid dreams during short naps (lucid dreaming is something I've been working on for quite some time, so I'm looking forward to seeing how polyphasic sleep helps me in that area).
