This topic periodically comes up around here.
What I have come to terms with is that while I can not discount the literature/myth/what ever it is considered, I can stick to what I feel and know to be true for me. For me to drink alcohol is to destroy my life. When I drink my life becomes unmanageable. When I don't drink and I practice and apply the steps and principles of AA in my life then my life gets better. I don't care if bread turns into alcohol in my body or if orange juice has an alcohol content. What I have found is that orange juice does not cause the obsession with alcohol that orange juice and vodka will. Since there are different types of alcohol I have to believe that the alcohol discussed in the article is not the type I am allergic to or that causes my obsessions.
