Hi Chip and welcome!
Though I know it wouldn't work for me I have seen a few around here that has managed to do what your suggesting. I don't see them back often so I can't say how it's working. I've know a couple of people who were able to maintain that way of drinking but eventually it escalated at some point. You may want to check out this link on moderation management and see if it helps.. on top they have pull down menu's you can use to see if it's an option for you.
