Hi, I too have been on tramadol, unfortunately (all of us being different) it stopped being effective after about 9 months – but that might be partly because my condition may have been worsening as well. So hang in there as long as you can! I found it a very good medication when it was working for me, and its successor is also good. So no need to worry too much, sometimes a rotation system works well, I gather.
Good luck, Jane
