I took Vicodin a couple of years ago for severe back pain. Since my accident three years ago I have taken Vicodin, Percocet, Morphine Sulphate and Oxycontin. Believe it or not the only one that I got addicted to was the Vicodin. I went through withdrawal symtoms one weekend when I ran out of it and my wife was holding me in her arms all night long like I was a heroin addict or something. It works but BE CAREFUL!
