Like others have shared, it's the body craving the empty carbs it used to get through booze.
Do what you have to do to stay sober, but I honestly think that continuing to indulge the beasts keeps the cravings lasting longer, because there is a chemical link in the messages to and from the brain when we eat empty carbs.
Options...and I truly believe they will help you get past the mad carb craving sooner, and the booze cravings as well. Drink lots of water. Eat complex carbs instead. Say no to cookies and candy. eat a baked sweet potato, or some nuts, a half a banana, a bowl of whole grain cereal. Add more low fat protein to the diet.
And remember that no matter how edgy we feel, drinking is never the answer. Temptation to drink will probably be a default setting for a little while, but we don't have to go there, we have the option of over riding it.
sugar is never the answer either.
I have eating disorder as well, so the above is sort of a mantra to me.
