I have spent years and years grilling my AH about his drinking. I have driven myself mad with this routine. He NEVER admits to drinking, and yet I keep asking. He is the self-admitted alcoholic who amazingly enough, never drinks according to him. We went to a wedding and I came back to our table to find him holding a wine glass filled to the rim with Merlot. He swore up and down that it was Diet Coke, even after I sipped it. This disease sucks the rationality out of its victims.
