For contrast: http://www.supermemo.com/articles/polyphasic.htm http://www.supermemo.com/articles/polyphasic.htm http://www.supermemo.com/articles/sleep.htm http://www.supermemo.com/articles/sleep.htm My uninformed take on this: If you will be depriving yourself of sleep anyway, polyphasic sleep may be worth a try. In this case watch your diet: eat more vegetables and avoid hard to digest foods. It's bad enough that you're abusing your body in one way, and there is a correlation between your diet and your need for sleep. [Edit: I HAVEN'T EVER DONE POLYPHASIC SLEEP SO DON'T TAKE THIS AS ENDORSEMENT.] What I do when I want to squeeze myself is - Avoid caffeine. - Crank until I'm pretty sure I'll fall asleep as soon as I go horizontal. - Sleep without an alarm clock. If I haven't gone wildly out of sync, chances are I'll wake up refreshed without oversleeping. - Take a 20m-ish afternoon nap iff I feel drowsy at that time. And two things I don't do but I'm sure I should: - Do at least 15m exercise early in the morning. - Eat light, varied foods with plenty of vegetables. YMMV!
