A number of people who formerly described themselves as "going hyper" -- I'm one of them -- subsequently found out that their jumpiness, hot and cold flashes, heart pounding was NOT hyperthyroidism. It was bromide detox.
I held onto the notion for months that I could only take a little Iodoral. When I tried the salt loading protocol, suddenly I could take way more iodine. And we all know salt doesn't cure hyperthyroidism! So it couldn't have reversed my jumpiness.
