i would go to
www.thyroid.about.com so many people there have graves.
i know two people close to me with graves..one had the radioactive stuff and the other had it removed.
what happens is once they stop the over activity...alot of times you go hypo thyroid and then take thryoid meds.
it does seem scary, but its more common than people think. i have hashimoto's hypothryoid. which is like yours in the sense that we have antibodies but it works in the opposite way kinda.
good luck and you arent alone...
btw both people i know are totally fine now!!!
