I didn't have an appetite for like 3 or 4 days the first week I stopped drinking, but eventually it returned a bit. I dropped alot of weight too from being deficient of all of the empty calories that I was putting into my system, on top of the lack of appetite. I think it's a pretty normal symptom.
I have read alot of people saying that once you stabilize/normalize, your appetite will come back 10-fold and you will get all these cravings. I personally am the weird one and haven't craved sweets like most others I have read, but I randomly began to crave coffee after not drinking it for a year and a half. I find myself drinking alot more too. It's like the body is trying to find its homeostasis sans alcohol, whatever that means for your body.
Keep up with the vitamins...I'm taking a multivitamin too to try to get as many good things in my system that I might not otherwise get by what I am consuming.
