Totally agree with Firesprite.
Additionally from my RAH experience, he went to addictions counselor who started working with him and my RAH insisted on of some kind of drug to stop his cravings (didn't work), then they did some anti anxiety meds which helped a bit.
The counselor suggested/recommended AA in addition to counseling. She helped him find some meetings where my RAH felt comfortable as he felt he needed to be with other "professionals". Anyhow he went and by however it works, it helped him be accountable. He since stopped seeing the counselor but goes 2x weekly to AA and hasn't drank in over a year.
I'd stay out of whatever thoughts your AH has, it's his responsibility and it's so easy to get caught up in the later blame of "but you said...." when they are not taking responsibility to stop their drinking.
Glad you are feeling good.
