I was diagnosed with Graves in March of this year. I started on 30 mg of Methimazole per day, then after a month went down to 20. My TSH has been suppressed this whole time, and my endo has clearly been dosing based off of TSH and not FT4. With a range of .7 -1.5, my FT4 has been:
3/30/10 3.90
5/14/10 1.03
At this point I bumped myself down to 10 mg per day, thinking I was heading hypothyroid, then:
6/15/10 2.84
so he put me back on 20 mg per day, and FT4 was most recently:
7/22/10 .61
Should I try 15 mg, 10? He told me to stay on 20, which I know is too high.
