@instajelly I tried polyphasic sleep about 10 years ago. I did a modified every man schedule- I don't remember the specifics now but basically I had one big bigger sleep at night and three super short naps. My problem wast social life- I was just starting to date the gal who would become my wife and if she wanted to do anything (or another friend had a LAN party, etc) I'd skip a nap. I think I made it only a couple of weeks, but it's still super fascinating to me.
