You sound like me, ive been trying VERY hard for the past 2 years to eradicate my hasimotos. Alot of people find a link between Candida and hashimotos eventhough i cant find an actual study on it. I feel tons better when i eat a diet only consisting of vegetables and fish/grassfed meat (basically a candida diet). Hopefully we will eventually find the answer. Are you taking Kelp? What is your diet like?
