Yes, I was taking Tramadol (1-75 mg, every 6 hrs. as needed) and it did "nothing" until some of the pain got less (which then, I didn't really need it, did I!) and I think it is habit forming even if not "addictive". Didn't even help make me sleepy so I could get to sleep when the initial pain was making that hard. I still have some percocet I don't need anymore if you want me to email you some :-)
