Iodine on skin- weird symptoms. please help

my serum Iodine is 50 mcg/L which is just under normal range. i also dont eat fish. ive been putting a drop of nascent Iodine on my skin every other day. when i do the brownish color vanishes within 30 min or so but i also get a drowsy / dazed feeling in my head. is this supposed to happen? in the past the same thing happened when i would take a drop of lugols Tweet
