I'm sorry but I think that saying doctors must have a paid interest in
armour, is total BS.  Since armour is so much cheaper than synthroid,
I'd say if anyone wanted to make money they'd invest in the drug company
that makes synthroid, since it's among the top few most Rx'd drugs in
the US.  ;-)

My dr. Rx's armour and I take my Rx to the drugstore like anyone else.  
He doesn't make any money off of it.  If I wasn't doing as well on
armour, he'd try cytomel or something else.  Basically the difference is
it matters to him if my condition is improving, not which drug I'm
taking or what the TSH is.

I don't know...it's only my opinion but if I were in your shoes I'd go
to someone else.  It just seems like when you try to educate this dr.
she won't listen.  The bottom line is you need to get clinically well,
not just look well on paper.  Anyway, good luck to you and I hope you
are able to get what you need.  :-)
