I just wanted to concur with Bobbi’s comments 100%. I had RAI back in April, went hypo in July and just recently my TSH levels are down to something resembling normal levels. I had a blood test last Friday and my endo has adjusted my meds (I’m taking the “S” drug) from .1 mg a day to .112! You wouldn’t think that .012 mg would make much of a difference but apparently it does.
If you don’t like your endo and think that s/he doesn’t listen to you it definitely pays to find one who does!
Hope that helps your understanding of this weird disease some.
