I don't know much about AA..and it doesn't resonate with me - but I'd never tell anyone that AA wouldn't work for them - no way!
Here are two people that you know and like (I'm pretty sure) who have both been helped by AA (see link below). Of course wherever one gets their inspiration be it 'god' 'the divine' 'good vibrations' 'higher Self' whatever - it sounds like AA help alllll sorts of people.
