I was also dx with Graves a year ago. After having CD for 8 yrs. My heart literally felt like it was pounding out of my chest and my hands shook really bad. After a few visits with the endo and been on Atenol and PTU i feel sooooo much better. I was just wondering. Has anybody taken the Radioactive Iodine? I have talked with the endo about this but i'm hesitent.
