Every body is different. Sounds like you are taking too much. If it has not cured you completely yet, then something else is going on that needs to be addressed. All you need after 6 weeks at 50 mgs per day is 2-3 drops per week, unless you are trying to cure a chronic lung condition. And then you will likely need other things for deep cleaning of the lungs. Inositol comes to mind. You are just putting the excess Iodine in the toilet. And your TSH will come down if you stop taking so much. Read about this, too-

I am taking 50-100 mg Lugols since 2,5 years. My TSH never went up ( if u use Instagram check #stephylabor ) . It only ever went up when i took less than 50mg. My last TSH 5 months ago was even super low 0, something.

Whenever i take less than 50mg my boobs start to hurt right after or even before my ovulation.

Some ppl take up too much toxins (unknown or not) that they need at least 50mg per day. Hidden Bromides, hidden Fluorides, other goitrogens and other drück toxins in body tissue.

I'm not expert but there are a couple of things that come to mind. (My TSH was 8.3)
Make sure you are taking sufficient amounts of B2 and B3. I took the normal dose but decided to up it at someone on CZs suggestion. Helped a lot.

Also, I think you should re check your TSH at a different point in your 28 day cycle. The TSH changes can occur due to other hormones.

The other thing that comes to mind is a food intolerance. If you are eating something that is irritating your system it can easily upset the TSH.
I know how crazy it sounds. Potatoes mess me up but I feel nothing when I eat them. Eight hours later I am coughing like mad and have huge amounts of phlegm. Try the Elimination Diet to figure out what the irritants are. It can't hurt even if you don't find the answer to the TSH issue.

I've talked to a dozen women who have tried the drugs and all of them said it just made things worse. The conclusion was always that you need to listen to your body.

Your body needs Iodine it doesn't need drugs. Grizz is sort of the Iodine expert on CZ. See if you can find and read his papers on CZ. You could private mail him.
