Kinda new to all this GD stuff – let me tell you, this board has been a life-saver, not to mention keeping me sane. Was diagnosed in June 09, and had RAI treament 4 days later. The dosage they gave me was 12.5, and when I saw the endo in Sept 09 he said it had been successful – was mildly hypo by that time. And have been on synthroid ever since – 100mcg was too much, and I became hyper again in May 10, lowered the dosage to 75 mcg and so far….looking good. TSH at .9….but optimal spot is 2…so if levels are still holding by Dec we will begin to ‘tweak’ a bit….am getting there – finally! So I don’t know if it helps to know that this particular dosage of RAI did what it was supposed to do. Am 57 years young (older on some days though lol)… Keep hanging in there…speak up for what you feel you need, don’t be shy. It’s your body and you know it better than any professional. And have faith that things will get better…. ” title=”Razz” />
