Thyroid (hashimoto)question

Hi guys!!! (**waving at all familiar peeps**)

I was diagnosed with Hashimoto last year and put on low dose of thyroid meds but after about three months I had enough of it and went off. Hashimoto is inflammation from auto immune so I figure there has to be a way to curtail the inflammation and yet meanwhile maintain a better rhythm with my thyroid. As it stands when I use the io (painting it on) more than two days a week I get hyper symptoms, when I use none I get hypo symptoms. Frankly I am frustrated and refuse to go back on the meds, don't care if it is natural or not had both and it sucks!!! So anyhow, I read something about zinc being deficient and causing issues with thyroid inflammation..anyone know much about this?
Yes, I am taking all supplements that are needed with the IO therapy and other stuff still. But really really want some stability with my body, it's up and down like a yo yo.
Thank you!!!! =)
