Yep. I have chronic back pain and migraines. Oxy-Contin is an extremely effective pain killer but it's just as effective at being addictive and a nightmare to get off of too. It's power shouldn't be taken lightly.
At one point, my back pain subsided somewhat so I got off OC for a while, which was the hardest thing I've ever done with regards to drugs. I got over-confident and worked my back too hard and messed it up again.
It was a hard choice to get back on it, but I'm on OC 40's now, three a day. I am grateful that my doc is great to work with...not judgemental.
