i am looking forward to the reply to your last post–it sounds exactly like what i am going through! i was diagnosed in january, and have been on ATD and beta blockers since then. i am scheduled for RAI this thurs 2/26. i am very, very nervous about the permanence of it, and especially about getting stabilized and gaining weight. i lost nothing, but had lots of cardiac symptoms. my big complication is asthma, which has gotten much worse since starting the beta blockers. my pulmonologist wants me off of them, which is why i’m not waiting to see if the ATDs can work. i can’t be on the beta blockers for all that time while i try to get in remission. i really like my endo, she is very patient, responsive and kind. she seems to be pro RAI, but is not opposed to long term ATDS. she said my levels were also 4x normal, and thinks that eventually i would need RAI at some point. looking forward to seeing more posts.
