Hi Susan,
We're all different. You have stuck to your treatment regime for so long, and are satisfied with the results. All the best to you!
Me, I found that my body didn't like having medication that produced such debilitating side effects, and fortunately I was able to find support for stopping taking it, backed up by current medical trials.
Your doctor apparently doesn't agree with applying the trial results to your case, and you are fine with that. Your choice. You might get a second, or third opinion, if you ever feel to take a break from Gleevec and see how strong your internal defense system is these days
As long as you are willing to live with the effects of taking medication for the rest of your life, with no breaks, we have your back.
Me, I have applied a different philosophy and am very happy with my results.
All the best,
ChrisC
