I don't know I had a lot of problems with pain control just being a hydro addict. I would be dead if I was ever able to get my hands on fentanyl or dillaudid. Seriously. I would not be here. I did try to move to oxy. I would take 8-10 10mg and it didn't feel like my hydro to me. I thought that was so weird. If I liked hydro wouldn't I LOVE oxy? Maybe I didn't take enough with my high tolerance. Idk. I'm glad it didn't work out though.
