I too am sensative to every med out there!!! Part of why I'm so scared of meds *hugs*
I'm glad your doc was so honest...but I'm sorry that he isn't the one who will be helping you witht his particular aspect of your well being from now on. It is SO HARD to find a good doc. BUT if he is giving you a referal...hopefully it will be for ANOTHER good doc and then you'll have TWO trustworthy docs on your side!
