Bev, I'm not sure how long it takes the iodine in the kelp to balance back out in your body. I know I have taken very high doses of elemental iodine and believe me it will rev you up. It took me a while to get back to normal but I'm ok now. As far as I can tell it didn't do any damage. You were not hyper to begin with were you? Give ML a chance to give an answer after weighing all the evidence.
I'm so sorry you are feeling poorly. I take only 3-4 capsules of kelp. I would be a live wire if I took more.
