A motivational speaker and a blogger versus the medical community and sleep researchers. I know who I'm siding with. Everyone I know who's tried it, including me, has ditched it after a very short time. You know the feeling you get if you normally sleep 7 hours and only get 3? Imagine feeling and functioning like that if you miss 5 minutes of sleep or have to stay awake for a full 6 hours. Yes, you will get more REM, but replacing several hours a night with 5-10 minutes 6 times a day does not give your brain enough time to do everything it does when you're asleep (and all phases are important.) Your daily routines will be screwed up, your appetite and fitness will suffer, your memory will suffer, and your alertness and concentration at important times will suffer.
