For me, the pain itself seems to be preferable to the pain medication. In the past I have had bad reactions to Donatal, Tylox, and Percocet. Basically, I become anxious and feel an uncomfortable detachment from reality. Last year I had emergency surgery and was put on morphine for 2 days while in the hospital. This was the worst experience ever as it felt like I was awake for the whole time. Its beyond me how anyone can abuse any of these medications.
I guess he point I am trying to make here is that since you can't "try before you buy" in this instance you should be preprared for your own reactions.
