I can't really comment on Armour (I am new on synthroid) but let me tell you starting synthroid is and was not a picnic! I got even MORE hypo symptoms ...perhaps when you first start on Armour it is like that, too. I am now on week six and it is starting to calm down a bit. One day at a time. They say about six weeks... I really do think the body takes quite a while to adjust. Well, anyway you are not alone with symptoms.
