Am sorely tempted to give this a try...

from Wired.com:

Turn your waking day into a 22-hour party by getting your shut-eye polyphasically — in a few quick bursts. Studies by the Chronobiology Research Institute show that for those on round-the-clock schedules — sailors, astronauts, gamers — it's more effective to recharge in short stints. For survival, the brain will eventually adapt by entering the REM state much faster. The cumulative result: a higher percentage of the best kind of z's.

Can't help but think that they're absolutely right later on when they say that, "The first seven days of deprivation will be sheer misery."
