Thank you so much, you are very gifted, clear and complete.
This boils down to one of those 'which came first, the chicken or the egg?' Being low thyroid is cause for many symptoms. Many symptoms are cause of low thyroid. I'm just ready to have normal thyroid to see which symptoms it can cure as I have already got two months going at it from the other direction.
I will report back any results I find going this route.
