Sounds like you doctors doing a good job, stick with him. All that I could add is that you really need some sort of 12 step program or support group beyond these pills; otherwise you will be left with the same problems you had before you started taking them, but without the medications to block the issues. I hope that makes some sort of sense, it's an importance issue, that goes way over too many peoples head. All they see is "getting clean, getting clean." They don't understand the utter importance of the WEB OF SUPPORT!
Try NA, it's worth a crack and as you've got a desire to be clean, you have a valid right to go to meeting right now, today, even before you're actually clean. The desire is all that's needed. And you don't have to say a word at meetings, just sit at the back of rooms and be quiet, that's often the best in your position, listen and let recovery soak in, whilst you dry out :-) Pick up the phone book and call them, it's that easy if you want it to be.
