★★★★☆
I get migraines. I typically get from 2 to 4 per month, and they can last up to 4 days. Often, they don't respond to either OTC pain relievers or prescribed tablets. For some reason, when I get a migraine, I crave salt. I thought it might be the iodine my body wanted, so I tried 6 drops of iodine solution in a glass of water. While it didn't cure my migraine, it did provide immediate relief, and as a bonus, I noticed I could breate more clearly, think more clearly, and had more energy. Don't know what the reason could be, but these results are consistent.
