corn, I think you've got some good suggestions here: see another doc who will prescribe some meds and discuss a home detox, or, probably better, try to find a detox center you can use over the weekend.
Also, I would consider the idea that you don't have to choose just one program. I still use an outpatient addiction center where I see a therapist, and I go to AA too.
Maybe there are outpatient recovery programs for people who have your diagnosis?
