I'm taking synthroid because I have no choice really, I have Hashimoto and my thyroid is broken, so I only replace with is missing and keep my TSH near 1, which is fine. But taking suppressive doses of Synthroid (or worst Armour) when you have real CFS (along with cortef and androgens), is a disaster waiting to happen. I started feeling HUGE fatigue and other symptoms on that regimen.
I'm better on synthroid only now, but those forums advocating large doses of armour, cortef and other hormones are dangerous for us with CFS. Problem is they have no way of knowing if we have real CFS or fatigue from thyroid resistance and they give treatment advices to vulnerable persons. I wanted to warn people of the potential risk of HRT and someone got pissed and minimize the reliability of the CCC definition, saying she had all the symptoms, but guess what, severe hypothyroidism cause similar symptoms, everyone knowns it. She had a case of thyroid resistance requiring massive doses of hormones to feel better, it's not my case, I feel hyper on a suppressed TSH quite fast. So she thinks because it worked for her, that it's the same for everybody and that CFS is thyroid resistance.
Bunch of crap, some people are damn stubborn, we DON'T have the same illness...!
