Tried adapting to polyphasic sleep, am off it for now. My critical weakness was waking up after core sleep periods - naps were east and effective though, and I found lots of great uses for the extra time (okay, math textbooks and videogames). I'm going to try playing around with what times in the 3-4 hour range it's easiest for me to wake up, get an alarm clock that produces light, and try again in a week and a half.
