I had my thyroid removed in 2007 after being diagnosed with thyroid cancer. Since then I have been taking Eutirox, 100mcg daily. I actually feel ok now, as I was having a lot of trouble with fatigue. However, my weight fluctuates terribly, and have a lot of bloating and now I am suffering with enlarged and tender breasts. I eat a healthy vegetarian diet so why am I having trouble with losing weight.. Is there any supplements or anything I can do to speed up my metabolism?
