I think that sometimes it takes a bit more than discipline, if you are going to really do it right. Sometimes there is an underlying medical issues keeping you from quality sleep (and leading to a delayed sleep phase) and other times it might actually be that, given your genetics or what not, you just don't sleep until later. I am a fan of "early to bed, early to rise." But for me it's got to be with a PAP machine.
