If they have no side effects that bother you, I'd say keep taking them so that you can look at the doc and honestly say that you did take them as instructed and that they aren't working for you. At least you'd know for sure.

It's possible the pills may have just stopped working for you. My tolerance for some pills is pretty high. I used to take sleeping pills and I stopped because I had to double the dose after only a week or so, and I take a lot higher dose of my transplant drugs than my cousin, who had his transplant only three months after me. It's possible your body may have adapted to what you are taking now and you may need something new.

I have learned that you do need to take pain pills as scheduled and not wait until you start hurting, because it's more effective to stop the pain from happening than to deal with it once things start hurting. The pain also creates unneeded stress on your body.
