Thanks, Diane!
My doctor has told me that the RAI completely shut down my thyroid function (and I can believe that, since I went from a size 4, to a 6, to an 8, then 10, and was looking at 12–all within 4 weeks of the RAI). He seems really confused–not so much at the fluctuations, but at the big swings with little changes. So, I continue, and wonder.
Thanks for your response. I, too, will print it out for future reference.
