Was at a meeting the other week where the person who set the meeting up was sober for 42 years through AA and was an atheist. Had a good chat to him at the end of the meeting and gained some great wisdom. If you want to get sober and stay happily sober AA is there for you and works. Besides, the program of action doesn’t require any meetings per Se.
“The spiritual life is not a theory, we have to live it”- this is what removes the drinking problem and gives peace and serenity in my experience.
If you’ve found a meeting with likeminded people that’s great but there can also be a lot learned from people who are very different; even if it’s that you know you don’t want to end up like them! Haha.
