Hi Melanie
Have you posted this on the Thyroid.about.com site? There are posters there whow could point you in the right direction. Frequently enough I see people posting links to websites for doctor's written by doctors. But it escapes me now what they are! (you know how it goes)
But on a side note? I was on Synthroid for only 9 months but I gained weight and it never made me feel better. EVER. Once I got on Levoxyl I started losing weight and feeling a ton better.
