I think it's common among friends and family to think that "if he just stops drinking..."
Someone here told me that addiction is fourfold: It's a physical, mental, emotional, and spiritual addiction, and recovery also needs to happen on all four levels. Rehab is just the beginning -- like getting a drivers license. This is when the real work starts, when he has to keep working on his recovery and deal with the stressors of everyday life. That's where the rubber meets the road.
I never got to see AXH in recovery, so I have no first-hand stories to share. But I've heard from other F&F that it is a rough ride, and that the best thing you can do is focus on YOU and your recovery.
