What thyroid pills are you taking?
Humor me - drop the dairy, no yogurt, no cottage cheese, only eat protein that is animal flesh or almonds/peanuts, no bacon bits, no nitrotech or any other bars.
ONLY eat greens and green veggies, animal flesh or nuts and an apple or two in the first half of the day and drink no less than one gallon of water for three days.
and report back, after those three days you can introduce some white rice (yah white not brown) 2 servings in a day 1/4 cup each. Then after three days of that report back again.
do not eat anything that comes out of a box (except rice), bottle or any other type of container (except the nuts).
DRINK A LOT OF WATER
