TSH also lags 4-6 weeks behind your medication adjustments. Your dr. should not be changing meds based off of your tsh but off of your Ft3 and Ft4 levels. Are you getting those checked as well?

I have graves. My endo would LOVE to see my tsh hit 1! But it's really irrelative what my tsh is as long as my FT3 and FT4 is where it needs to be. Because I have an autoimmune disease, my tsh will be naturally suppressed, yet most endo's focus and treat off of tsh levels. Be informed. Have you ever checked out the mediboards? http://mediboard.com/groupee/forums/a/cfrm/f/470109542
There's a lot of good information here.
