When I first got sober I ate ice cream like crazy. I couldn't stop. Needless to say I never lost weight like so many do when they quit drinking. It's just your body craving sugar and it's normal, at least for us. Don't worry too much, ice cream doesn't do anywhere near the damage that alcohol does. The sugar cravings will go away in time. I had to switch to sorbet. And now I no longer eat either. Hang in there.
