Get the Iodine you gave her back from her. At least you can take it and it won't end up in the garbage can. Better you take it and it doesn't get wasted. It could be a detox symptom she had, it also could be she contracted a nasty bug at the same time as taking this, it is still cold and flu season. You are right, you can't change people who don't want to change. I have talked till I'm blue in the face to people to try to help them. People aren't willing to quit eating shitty food and eating whole natural fruits and veggies. They won't even consider taking vitamins and herbs. And getting people to cut out foods that are processed, preserved, colored and flavored is like pulling teeth. Their loss. Too bad it will probably come down to loss of life eventually because they aren't willing to research for themselves or even listen to others who would do the research for them.
