I was on Tramadol five years ago for post-operative pain. It worked a treat and made me feel wonderful, but it's pretty addictive and it gives you terrible constipation, like all opiates. As of this afternoon, I've been on 30/50mg Co-Codamol for taking the edge off the pain of a lateral malleolus fracture of my left ankle. It's passable, but nothing like as good as Tramadol.
