Iodine CAN give you the runs, for the same reason that antibiotics often will. Iodine kills all the microcritters, and if there's enough of it in your drinking water, it will neatly kill all the intestinal bacteria just as neatly. Ooops, no bacteria, the gut stops working right.
I'm not sure how dosage-sensitive that is, can't seem to find any information on the web about how much is too much that way.
