Just wanted to let you know that before I had my TT, my hashi gland would not let me even tolerated 12.5 mg of Synthroid! Now, I'm "even" on Unithroid 100 and cytomel 2.5. I am still tweaking my meds and not perfect by any means, but definitely more even. It's amazing how Synthroid gave me a "tight" or "gripping" stomach feeling, and Unithroid doesn't at all--that's why I switched. You may have to play with dosages AND with brands. But, once again, my hashi kept me from tolerating any meds before.
