welcome to the back board! I have been taking Tramadol (Ultram) for over a decade, I take 300 mgs a day and have done so that whole time.
They still are effective to me, and since I have been told my pain will be lifelong, I will probably be on this medication for the rest of my life.
I know I am physically dependent on this med, if I stopped taking it, I would feel sick and could even have seizures, unless it was properly tapered.
But thats not the same as addiction. addiction would cause me to take more and more trying to feel high, the best way I know of to know if youre okay or not is just this, Pain management gives you back quality of life. Drug addiction destroys quality of life. Only you can make a decision about if you are addicted or not, but you certainly arent automatically addicted when you become physically dependent.
Good luck, I hope you are feeling better soon.
