Welcome, Paganinfidel. I too stopped drinking by applying AVRT (although I have knowledge of AA). I found this link in Secular AA, the sub-forum below this one, posted by CousinA:
Secular AA. (Secular (Atheist/Agnostic) AA Meetings)
There’s also AA Agnostica, which can be googled. But if you’ve any questions regarding AA alternatives, please ask.
