I don't know that you are necessarily wrong. OCD comes in many forms and I can see why you would see a link between that and alcohol. I was diagnosed some years ago because of a disorder I suffer from called "dermatophagia". It literally means "skin eating". I bite, chew, pick and ultimately swallow the skin on my fingers. It is disgusting, embarrassing, painful and yet I cannot stop. I will be bleeding horribly and I continue to bite. My hands are so scarred, I hate it. It is apparently a form of OCD.
