I am sure that a few recovering A's will drop in but from what I have learned the most important factor is the A's desire for recovery. A's have many avenues for support not just from families.
If family support was all that was needed the long term recovery rate would be much higher than it is. My exah has family and friends who would support his recovery but he has to take the first step. He refuses to even take one step into a meeting let alone detox or rehab because he wants to continue using not because he does not have a support system.
