It comes and goes for me too. Somedays I feel like I'm stalking the dogs with 2 slices of bread, ready to clap them into a sandwich. Others, like yesterday, I ended on 902 calories and not even hungry.
I congratulate you, though, on experiencing the feeling that you don't have to stuff yourself with everything in sight, just because you can. It's a great sense of liberation, isn't it?
