Today is my 4th day of using polyphasic sleep. I am using the Dymaxion Sleep Schedule which calls for 4 naps each 24 hour period and 30 minutes during each nap. Thus, I sleep for 2 hours every "day." So far, I have felt great. My mental and physical capabilities have been stellar, and of course I have had a ridiculous amount of free time which I love.
