Polyphasic Sleep

After my own experiments with my circadian rythm, I recently found Polyphasic Sleep. It's also know as the Uberman Sleep Cycle and is a method in which one sleeps 6 times, every 4 hours, for 20 minutes, during every 24 hour period. Why? Well, only sleeping 2 hours a day instead of 7 or 8, give you 3 extra months of awake time each year! The blogger Nick Busey is attempting to live under this sleep schedule, and is logging it all in his blog Ubersleep.
