Not enough time? Enter Polyphasic Sleep

Hello everyone. I was wondering if anyone here utilizes Polyphasic Sleeping cycles?
As a college student, I'm pressed on time just from the courses I'm taking. When you factor in going to the gym, having a social life, and then trying anything IM-related.. it almost seems like there's not enough time in the day.

I'm considering going on a polyphasic sleeping schedule. Has anyone tried it? Did it improve your IM endeavors?

For those who aren't aware, basically the only important part of sleep is the stage 4 REM cycle. However most of our sleep in the conventional 8 hour/day (monophasic sleep cycle) is wasted, in the sense that not all of it is stage 4 REM.

There is a way to trick your body into entering REM sleep as soon as you hit the sheets, which allows you to function even more efficiently while getting less hours of sleep.
There are a few different cycles (5 I believe) which can include taking 2x 90 minute naps, and a 3 hour 'sleep'. Or even just taking 6x 45 minute naps.

There are a few scientific studies and blog reports on the topic. It works, and you only need 3 hours of total sleep. That leaves an extra 5 hours a day... 35 hours a week.. 1,820 hours a year, and roughly 127400 hours of your life (Assuming you start now). That's 14.5 years you would have spent asleep, that could be utilized more efficiently.
