oh and TJ, your going to want your doctor or something to give you something to let you sleep. The first few days its almost impossible. But that goes away. But for a few days you may need something. I take remeron at a low dose which works for me whenever I need sleep. PM gives me those, says there are very safe. I don't know if you got addicted from real pain, but now I have to deal with the pain again, the headaches that I had are back. The only thing that works is opiates, but I haven't been good about controlling how often I take them, since i'm always in pain. Let me know if you have any other questions about sub. I've done a lot of research
