Like Cynical One, I would just make sure that you have a variety of alternatives available. I would still offer a nice glass of wine or beer to guests that drink responsibly. Recovering addicts still live in the same world as the rest of us, I don't think they expect that everyone everywhere will modify the environment for them.
Hmm. On the other hand, a world where everyone modified my environment such that I never saw another piece of pecan pie might benefit me greatly, but what a sad, sad world that would be.
