I got dui's in 2005 and 2014. When I got my second one I had to go to work furlough which is kinda like a low level jail where you can leave for work. While I was there I had to attend several AA meetings they conducted at the facility. It wasnt for me because I didnt want to quit drinking, I just wanted to become a responsible drinker. The other part that turned me off was like Stargazer rex said, its very spiritual and if you are an atheist like myself, you might have a hard time with that.
I told my roommate that I was an atheist and he said that I needed to read the chapter from the AA book that was written for Agnostics. I gave it a read and it basically says that if you dont believe in god you are wrong but dont worry, lots of members have been wrong about god but they find him eventually. It literally says that it is impossible to beat alcoholism without believing in a higher power so AA meetings will help you work on your disbelief too. I found that off putting.
Best of luck on your journey.
