I am on 150mcg levothyroxine daily, which I take at at night. Take various supplements, have had this for 10 years. After 2 years of constantly telling the docs that I was exhausted all the time, they finally did blood tests. I am very anaemic, due mainly to still having regular heavy periods, also being badly hypo. Take a couple of iron tabs per day, just keeps the level from being 0. I am so sick of just not feeling any better, life is just not the same. So going to see the doc at the end of the month, and going to insist on T3, cytomel cynomel or the proper name liothyronine sodium. See that most who take this with their levo, makes them feel so much better. I am not overweight, but watch what I eat, no gluten, no fruit, very few vegs, coz of the goitrogenic effect, even when cooked, they affect me. So find that my diet is based on meat, bit of cheese, and lots of salads, with coconut oil and extra vigin olive oil. Has anyone in Newcastle had any positive results of getting T3 from their docs. I have a small computer shop, always get into medical discussions, ever so many of my customers have the same problem, usually women, but noone yet has been on T3 and levo.
