As to why you wake up hungry, it is likely because you eat only complex carbs before you goto bed. I'm not saying it's bad, but just that carbs are digested very quickly, whereas more fatty things take longer digest. With that in mind, most people that eat fatty foods sleep longer (you'll notice that now, if you didn't before.) My diet got way off track for a while, high salt, high fat, little green: I was always tired, always feeling snacky (a salt addiction I think). But since I changed what I eat, things have been getting better, and I really don't require as much sleep as I used to. I rarely wake up tired anymore, but I do wake up hungry, and well that's what breakfast is for hehe.
