Well, congrats on Day 6!
I'm not surprised that your focus is going towards your ED. I did have a pretty long period of sobriety back before I started to recover, and the thought that I might lose weight was a definite factor (though not the only one). I was living in a crazy environment at the time and I would go out for extremely long walks just to get away from it for a while. Those walks had a pretty profound effect on me because they gave me space to think and made me realize that I didn't want to die. Before that I wasn't so sure.
It sounds like you could use some time away from the house if you can get it. Even a 1/2 hour walk would be good.
And if your husband doesn't want to hear about your cravings then screw him - you can some talk to us!
