I've been reading about this sleep system recently and it seems very interesting. Basically, the idea is, instead of sleeping for a long time at night you take six 20-minute naps at 4-hour intervals throughout the day. Supposedly the first few days are horrible, but once you get used to it, it's better than normal sleep. Does anyone here do this or know anything more about it? Thanks It's actally called "polyphasic" sleep. "Monophasic" sleep is "regular sleep." My mistake.
