I saw an article that debunks a lot written by a doctor, that might be biased but it's still worth a read: http://www.supermemo.com/articles/polyphasic2010.htm

I saw an article that debunks a lot written by a doctor, that might be biased but it's still worth a read: http://www.supermemo.com/articles/polyphasic2010.htm http://www.supermemo.com/articles/polyphasic2010.htm Don't get me wrong, I've tried it, and failed like many others before me. I'd tried the uberman method for about 2 weeks before falling, and I didn't feel very productive during that time at all (although there were times that I felt more awake than I ever have done, and time seemed to merge, days didn't exist... it's a weird feeling) I've now adapted the old version of polyphasic sleep, take a nap in the afternoon and sleep for about 6 hours on a night and it seems to be doing me well :) But! I am tempted to give the uberman method another try, and I will write about it if anyone would be interested?
