Most of us deserve to be treated better by ourselves! That includes eating better.
I do better during the week because I work. I take my lunch bag full of goodies and when it is gone, no more food. We don't have vending machines, nor do folks bring in very much. When I am home, I tend to snack. I eat good stuff, because that's all there is, but still...Also, I tend to be cooking things for portioning out and freezing. There is room for snacking in that arena, too.

I do the best I can with what I have to work with.
