When diagnosed with Grave's disease, were your TSI antibodies positive ? If the answer is yes then you should be on Tapazole for life, you should never stop it, you were in remission because you were taking the Tapazole, once you stop it, you will return to be hyper again, if the Tapazole causing you some problems, there are other alternatives such as RAI.
Tests should be done at least six weeks after each change in the dose or the medication.
Best of luck,
