You're craving the sugar because your body needs it right now. Booze contains LOADS of sugar, and now that you're not getting it, the body is crying out for some. You're actually having a form of withdrawals.
Eat chocolate. It does help with this craving. Don't go overboard, but it helps with the craving for booze and sugar both. So keep chocolate around to help with both.
I wish you the very best. Take care and God bless. Hugs, Lee
