I have never been to AA so can’t comment on it from personal experience. From what I’ve seen here it works well for some and others not so much.
There are lots of people here who got sober without a formal programme in place. This community has been my main sober ‘fellowship’. I started going to Recovery Dharma meetings (mainly online) last year and I like it. Haven’t done the programme in depth but I like the approach.
Edit to add - I host an RD meeting and we specifically say no cross talk. I think there absolutely is a place for getting and giving advice in sobriety but personally I really appreciate having our shares as opportunities to hold space for each other.
There are lots of other resources and support programmes out there too - more here:
