Agreed. AA is a religious program, and if you're not religious you shouldn't do it. It's also not backed by sound medical research, and about 50% of people drop out after the first 90 days.
What is effective about twelve step programs is the support network you build. It's important to have friends you can call on when you're thinking of going to the bar, or just want to take a walk or try something new.
I think we've all been at a place where we feel that we're using something a little more than we should. Please remember that addiction is a behavior. When you talk with a psychotherapist and get real professional medical help, which you absolutely should, they will help you identify the triggers that cause you to drink. Maybe you're stressed and drinking allows you to relax. Maybe you feel overwhelmed and drinking lets you feel in control. Maybe your parents were alcoholics (mine were) and your drinking fills a void. Whatever it is, there's a real reason for your drinking and uncovering that reason is the key to your sobriety.
Alcoholics Anonymous and other 12 step programs have a high drop out rate (about 50% within the first 90 days) and are not backed by science, so you should talk with an addiction medicine doctor first (and go through an appropriate detox program).
That said, what makes 12 step programs effective is the support community you build in them, so find some people you feel safe talking with and who you can call anytime. In fact, find as many of them as you can. You have ~200 people on HN who took the time to comment, so there's a start.
