The reason the site exists is because doctors dont know how to treat thyroid and adrenal problems.Most of us are on our own,its a big scandal just like mercury,powers to be want to keep us ill. T4 never works,i was on it for12 yrs, i thought it worked bt did have so many symptoms,like constipation,dry skin, low stamina,candida,blurred vision but my endo put t down to other things not anything to do with thyroid. I was then prescribed prozac which nearly killed me,it has fluride in it aswell, not good.Lucky i was only on it for a couple of weeks,i scared my doctor with my symptoms, he told me never to touch it again,he took the packet away from me.
If you have underactive thyroid,its likely you will need treatment all your life mercury or no mercury. there are people on that site who have had their thyroids destroyed by RAI, after that the thyroid is never coming back, as i say the site exists cos hres nothing else, there are a few good docs but they are expensive.
