I'm not prone to being an alcoholic, so who am I to comment? But it occurs to me that you didn't cringe at having a couple sips when your boyfriend poured them. So maybe you can't handle a "single glass" but could handle an ounce just for the taste. Please don't even try it, though, if you think there's the slightest chance you will relapse: You have too much going for you now to relapse. You have become an honorable person!
