you did not say how much Iodine you are taking. I am an advocate of starting small (less than 1/2mg) and slowly building up to the Dr. Brownstein goal of 50mg/day http://tinyurl.com/iodine-references
I agree that what you are witnessing proves your body is absorbing the iodine. All detox symptoms are temporary, and you can do the salt flush & Pulse Dosing to help clear detox symptoms.
