Welcome to the club and so sorry to have you have to join. I have ON too and I am on hydromprphine-both the 12 hour one and the 4 hour one right now. I am having horrible insomnia from it and no appetite. Does it bother you at all? I take sleeping pills but they mostly don't help.

I see a pain specialist and had one surgery in Nov and am having another in 3 weeks.
