I think you are on the right track with your thinking as far as what could be causing your cravings. In early sobriety I ate alot of candy. For me, I've switched to a healthier diet lately and I still have sweets but I limit them. Sometimes I crave more and I give into that, then I am sorry afterwards. Better to have a sugar hangover than a booze one I guess. lol I don't know exercise and being outside seems to help me.
