Me too! It's almost 7:00 and I now go to bed at 8:00 - LOL. I think it's just boredom though -- I really don't "need" to eat. My guess is the body is so used to eating every few hours or so, that we're totally shocking the system. When you look at pre-cleanse, what did we do? We ate for entertainment (I did anyway...eat/drink, eat/drink). Now I have to find other things to occupy my time. All I can say is my house is awfully darn clean!
I am also "living" on this MB -- it keeps me motivated!
