It is a pleasure reading your positive attitude!
I heard/read few interesting things on Hashimoto's lately.
You probably know, medicine does not advise taking Iodine while having that condition. Turns out alternative medicine has found that Iodine can be taken with success, but only in combination with Selenium and Boron. Which is advisable aslo, when supplementing Iodine in people with deficiency only. You may be interested in Dr Jerry Tennant's research, easiest will be to find his videos on Youtube.
I benefited from them, since he summarized so many things I already knew in a very elegant and logic system about how body works and why we get different dysfunctions and conditions. The "introductory" video would be: http://www.youtube.com/watch?v=ZNUadiiLB5g
At some point, during the interview, he talks about voltage, iodine, thyroid, energy system of the body etc.
