hashimoto's disease
"I have been taking levothyroxine for 3 weeks and a day. I have fought my case for 12 months trying to argue I needed the medicine because of my quality of life. My blood read normal, however antibodies were present.
Since taking the tablets I have better skin, less constipation, sleep better, happier, much less tired, have not gained weight despite eating much more over Christmas! And the most unbelievable reduction in my acanthosis nigricans - the black marks round your neck, under your arms etc. my skin was like leather and almost black. Much paler now and skin is almost normal to touch. 
The specialist said he recommended I ate more fruit and veg. Taking this tablet has improved my life already. Please persist with your doctor! It's worth it"
