Hey,
I just started the process of stopping 3 days ago and so far am alcohol free. I did lose my apetite and it's slowly been coming back over time. I also lost about 5 lbs in two days and was more anxious and cranky. I still feel a little anxious and still a little cranky. I think it's a normal part of the process. One that you have to realize, at least I think so, that it's alcohol's sneaky way of trying to get you to come back to it easily. From what I understand, when you have been addicted, the survival part of your brain thinks that a substance is necessary for survival, while the more human side with emotions, knows its not. From what I have read, it sounds like the first step is taming the survival side and letting it know, you can survive without alcohol.
In summary, I think what you are going through is normal and that you must continue to do what you are doing in order to beat it.
I hope that this helps some.
