Last Aug. I was diagnosed with Graves'. With much research (on my own) and asking questions to my Doctors I'm still unable to find out WHEN and how long it will take to get my levels balance. I was give the radioactive iodine in Sept of 2005 and to date still go from hypo to hyper due to the inability to find the right amount of Levethroid. Does or is there someone out there that can give me some help insight. I feel hopeless at times.
