Great post. I myself use this method but i tend to sleep a little longer than 30 minutes and a little less in the night. If i sleep less than 5 hours in the night i might aswell kiss the next day goodbye i am a hopeless mess. But if i sleep for about an hour in the day anytime from 1 to 2 and have 6 hours at night i am like a spring chicken,lol....but it depends on age and don't forgte how cute you are that helps,lol..no but seriously age is a big factor, the older the less is needed.
