At least you will be making progress through the duration.
Honestly, you may be making progress with how much iodine you have in your thyroid, but you could be making yourself worse in other areas from mercury redistribution. I would judge this based on your reaction to iodine. Listen to your body and don't keep on taking something that is making you feel sick. If you feel you need iodine then you can even take like 1/5 of a drop of lugols which is still much more than most people get daily.
Remember birdlady? She ended up losing hair and getting a lot sicker from taking large doses of iodine from what I remember.
