Whatever you choose, AA, alternative to AA, or therapy, or a rehab program with the Minnesota method for example, (based on AA twelve steps), the point is that choosing some kind of a program is the way to go.
The alternative is to try and do it alone and very few have success with that.
My own "program" started with a visit with my doctor for liver levels. I then contacted an outpatient rehab program and started seeing a therapist. I also began AA at the same time. I still see the therapist and still am in AA 18 months later.
