I am not familiar with the treatment you are talking about but I had been taking propanolol daily for a long time for anxiety. It helped for a while but recently it hasn't made a difference at all. When it did work it mostly just calmed me down to the point where I could relax and let the anxiety attack pass. I don't know why it stopped working for me, my theory is that with starting college the stress and anxiety got to be too much for it to help. I now have to take klonopin or something like that.

anyway, I would look more into it and talk to your doctor about it. it sounds like something that could work from the little that I know about propanolol.
