Trying to get my head around this, went to see my consultant today and he says I would be better to have RAI to treat my Graves as my TSH is 0.1 and my T3 and T4 are off the scale,I think he said -55/ 68 ? ..... he has now upped my dose of carb to 40 mg 4x a day from 5 mg 3x a day, has any one on here taken that dose ? And how did they feel .? And has any one regretted having RAI and why ?? Sorry for all the questions .
