Still an old thread but I thought I would update. After trying to deal with the Graves Disease and hyperthyroid holistically/naturally, I finally got sick of living with the symptoms and taking tons of pills/suppliments and dietary changes. I opted for the iodine treatment. Within a week I felt better. Than slowly worse as the thyroid goes from hyper to hypo as it's dying. There were 3-4 weeks worth of feeling great when the thyroid levels were perfect. But once they dropped 0, I felt like crap. Muscle cramps and spasms that really hurt my bike commuting and hockey. I think I dropped to 0 ahead of schedule because of my activity level, but it was perfect timing. I started the meds this week a day after the worst of the hypo symptoms. Hopefully the thyroid pill gets me to normal physically. It's good to read above that there is a triathlete taking the pill.
I still feel it's best to go for holistic/natural if you have the time/patience to find which works for you. Small changes can have drastic effects over a 3-4 week period. Sometimes even in 1-2 days. But it's a long process to find what works or doesn't work. I just got tired of it and not always being able to be active with decent and consistent physical performance.
