I'd give it a try anyway. Your body might have the opposite affect, who knows? I tried it years ago. It took away the pain but I laid on the bed and gained 20#. He added Lyrica to it and I didn't do any better.
After a few years of not taking it, my current doctor put me on a low dose of liquid doxepin and it works for me. It's a very old drug so the young pups don't like to prescribe it.
