During the six months I was on methimazole, I felt awful but after the TT, the first year on levothyroxine was much better; however, even though my levels were within normal range, I still had complaints of anxiety, headache, muscle aches, etc. In my case, and this is not true for everyone i am sure, my “Aha” moment came when I went back and looked at my thyroid levels from annual physical exams long before I had Graves and found that sometimes they were mid range, sometimes higher or lower. As these checkups were routine exams, mainly for PAP smears, with no physical complaints, it dawned on me that since I did not even notice these variations then, why were they affecting me now. I have always had some anxiety, get migraines, have aches and pains, long before Graves. So I got my TSH at the value suggested post TT level, between 1 and 2 ( approximately, can be a bit over or under) and keep it there. If I feel I am a bit more anxious or achey or more headaches, I think of thyroid levels as a last consideration, not first. I found my anxiety over my levels was working against me, definite mind body thing. That is just me, everyone is different, and should my resting pulse exceed 120 or my hair start falling out by the handful, I would for sure get interim labs, but other than that, I have given up on “fine tuning” my values. These levels are not obtained in a vacuum, they naturally vary a bit by lots of factors like stress, illness, weight, season, etc so for me, so if within range of .5 to 2.5, I leave it alone.
