I'm going to add to this that expectations of how D should achieve his goal of not drinking harmed me. I spent a great deal of wasted time using info like him not having face to face support to try and glance into a crystal ball. It was totally wasted energy, simply being supportive of real effort was enough, particularly the real effort that followed a lapse in his plans.
I truly hope the number of people on this forum that believe it's AA or die have very much dwindled over time - I certainly can't remember the last time I heard it said here.
