I stopped it because it messed with my mind so much, and that it was given to me to "prep" for my future nerve surgery to "condition" the nerves. I guess what that meant was it was given to me because doing a "nerve release surgery" was only going to cause, at least for a while lots of nerve pain. But I decided I didn't want such a drug in my system just to "reduce" a little pain.
It seemed to cause a general numbing, sedation, and cloudiness of my brain, which I didn't like. I was always increasing the dose. So as soon as I got used to it, I was to take more, and more. Sounds like for you though this has some benefits.
I stopped it before I found Sarno, to be clear. But when I got off it, the pain did not change. And I never had the surgery, thanks to Dr. Sarno.
