shmookey asks: "Some people have adopted some unusual sleeping habits, which they believed help them work. The concept is simple: be active for a few hours, sleep for half an hour, wake up and then repeat. This supposedly maximized your effective REM sleeping time and cut back on wasted hours of idleness. Hack-a-day has a nice article and some links on this, which re-ignited my interest. Does anyone on Slashdot actually do this? How do you make it fit in with earning a living? What sacrifices do you have to make to live this kind of lifestyle?"
Called polyphasic sleep, or "The Uberman's sleep schedule", this is not something to dive into lightly, as it requires rigid scheduling, and there may be unexpected complications and other issues. Has anyone tried this? What were your experiences?
