Methimazole: Only blocks formation of new thyroid hormone. You still have a ton of already produced and stored thyroid hormone in the thyroid gland, which will have to be excreted and metabolized over weeks to months before you are better. In addition, your Methimazole dose may need to be increased. Free t3 (liothyronine) is worthless -- follow tsp. Your doctor can advise you.
