You don't NEED AA, I am not religious at all, nor have I continued to attend AA after the first few meetings, it wasn't for me, and I am doing just fine. What you do need is the resolve to quit drinking, and plan to get it done. For me it's important to stay on the forums on here and sites like this so I don't forget why I quit, and so I can try to help others. It's good to be active in the sober community when developing new habits and breaking free from your old ones.
