Sinus infection cured by taking potium Iodide!?

I read an article online about Potium Iodide. It said that is very effective in killing certain types of yeast and fungus. I was once a sinus sufferer so, I thought I would try it out. No Antibiotics could help my infection. I spent time at the ER and in the Hospital for Sinus infections. But the Potium Iodide cured it! Now, I know that Potium Iodide works on the Thyroid. They say you should take it during a Nuclear attack sense it blocks radioactive Iodine from reaching the Thyroid gland. I also know that you are not supposed to take it over a long period of time. I only take it about once a week. I take the maximum dose only once a week now. Has anyone else ever tried this?
