Well, it would be interesting to hear from others. I am not sure what the definition of alcoholic is, but certainly alcohol was part of my life, perhaps to anaesthetise reality a bit. However when I started fasting, I didn't even think about drinking, the desire just seemed to slip away without notice.
However I was never one of those people to get the shakes or anything like that, or want a drink in the morning. So I don't know how fasting would be for someone like that.
