Is rehab a long-term solution?

Hello everyone. I am a binge drinker. I can white knuckle 3-4 months and then drink.

I went to AA and got 9 months then stopped going and obviously drank again. I drank moderately for a few months. Now it's bad again.

I stopped recently and am back in AA and therapy. But my mum wants me to go to rehab because it worked for my aunt and she keeps on pushing it.

In theory, I'd be happy to go to rehab but I feel I don't need to be taken out of society. In fact, I need moderate help (AA) for the rest of my life. I don't need help getting sober, I need help staying sober.

Just wanted to get your guys' thoughts on rehab's long-term benefits vs weekly AA and daily mindfulness.

Thanks!
