Your doing great! Just remember there are a lot of diaries out there and people are trying to be active more (thats what I keep telling myself) rather than sit on the internet.
As for eating while sitting around at night... I in Grad school, so this happens to me often. I just drink my water... pretty much constantly. Sometimes your
body mistakes
hunger for dehydration.
Just a few thoughts... I have to go get the mother load of reading done this morning.
