Larry, I don't have a lot of time to post something long right now, but I wanted to answer you question: at my worst I was taking 10-12 7.5mg hydros in one day....that is a lot. My liver enzymes and everything else came back normal recently too. I am so glad I didn't do permanent damage with the addiction. I'd been on them for 1.5 years continuously (off and on at times before that but not addicted then.) Though these higher doses were toward the end. At least you know that your body is ok and feel less anxious about that as you contemplate your recovery. I'll post more later.
