Unfortunately, no matter what kind of dr. YOU go to, it is not going to make HIM stop taking the pills. However, I agree that learning more about addiction is always a good thing.
I'm a recovering addict. Crack was my DOC (drug of choice), but prior to that I abused a ton of opiates, and had built up a tolerance, as it sounds like your husband has.
As cynical pointed out, the person you need to focus on, right now, is you. You can't control your AH or his addiction. We talk, here, about the 3 c's...didn't cause it, can't change it, can't cure it.
I hope you continue to read and post. There are some supportive people here, with a lot of ES&H (experience, strength & hope).
Hugs and prayers!
