Bella, I attended an IOP when I got out of rehab but I found AA much more productive. The group in my IOP was not really focused on getting and staying sober; really they all seemed to just want to talk about how hard it was to get sober and nobody really made any progress - they just kept taking baby steps then slipping up. I needed much more than just baby steps. I ran screaming back to AA. They are focus more on a solution.
