Hi Mona, Your #2 message posted just fine! I was also diagnosed and treated with RAI back in 1991/92. And yes, it CAN be a difficult road back to normal(whatever that is) Over the years I have had my dosage increased from .1, to .125, .150 and now .175 of synthroid. I still struggle with feeling tired, muscles achy and the mental depression. I finally went to a shrink when I thought I was losing my mind and she assures me that being the slightest bit unstable on synthroid WILL cause all of these symptoms. It has helped me to plead with my endo and get my shrink involved so he would agree to monitor my labs more closely as I try the increased dosages. I know it helps to be able to TRY something. So, you are most definitly not alone, Mona. I find it comforting to read this BB each day, and bet you will, also. How has your treatment been going? Are your levels stable yet? Could it be that you are still “low-normal”? How often do you go cak for testing? Take care! Debbie
