I have also been on tramadol for awhile now. Any type of opiate that I've ever been perscribed has eventually worn down and the body does build up a tolerance to it. But you should never use more than what your doctor perscribes for you. I would go to your doctor and talk with him about how what he is currently perscribing for you is not cutting the pain anymore and I'm sure that he will up your dosage or perscribe you something that will be stonger. What are you taking it for and what is the extent of your injury? I have to take tramadol in the morning and during the day and in the evening I take hydrocodone. I've had to up the amount from 5mg to 7.5 to 10 of the hydrocodone because my body went through the same thing. Just be careful...these pain pills are pretty addictive...you always want to make sure you are taking them to ease the pain and not take more than what you are supposed to....just talk with your doctor and you'll be fine. If you need anything else....there are many wonderful people here who can answer all types of questions for you. Welcome to the boards!!
