It took a long time for me to get to the right MMI doseage. At one point I had to be checked once a month, I was very reactive to minor changes of the doseage. So hang on in there.
I was diagnosed becaus my heart was racing and I kept loosing weight, so my PCP asked for a TSH, FT4 and T3 plus anitibody check. Then he referred me to an endo and the endo had me have a TRABS test and a nuclear medicine exam and all that confirmed I had Graves disease.
And now, after 5 years, I seem to be in remission and am tapering off the MMI.
So there is hope at the end of the tunnel.
