Best and only medication that resolves my pain. I have taken this drug on and off sunset 2004. I can take as needed and there are no side effects for me. I am 75 and would have a life much restricted by pain if I did not have this drug. I fear Cymbalta, Lyrica etc as they mess with my head and cannot be taken on an as needed basis. Everyone is different. I hope you find what works for you.
