I have heard of this problem and read that many alcoholics are allergic. Years ago I had a physical craving to drink alcohol but learned to limit myself to one beer a day. I did Clark's parasite herbs and the craving disappeared. Alcohol free for about 10 years a friend talked me into having a glass of wine for our 70th birthday celebration and a few hours later I developed hives. No wonder I felt ill after drinking, gluten in the beer and a reaction to alcohol.
