I too have been diagnosed with Graves, although mild. I'm on 2.5 milligrams of tapazole. I don't know if I could have gone on much longer without it, and I'm not that bad. The symptoms of hyper were so awful, I had to have some relief. I couldn't take beta blockers so it was awhile before I felt better. I don't think excess thyroid hormone is too good for your body (heart, bones etc...) make sure you find out all this before you make a decision to do without meds, this can be a crazy disease, and you could go into thyroid storm if levels get too high.
