Sounds familiar to me, my AH drank so much in his past that his insides should be "pickled"; however, he too has chosen to "moderate", "cut back" if you will. Its all the same, he is still drinking, even hiding his stash.
We will all sound like broken records and say the best thing is to worry about your recovery and not his problem. Find help with support groups like Alanon or a therapist. This site is wonderful and can guide you. I could also recommend the book Codependent No More, it is an excellent resource.
Keep on sharing and take care!!
