for your coments and suggestions. I pm'd some additional info that might be helpful but I'll certainly follow up on your suggestions. Fortunately, my thyroid functions, TSH, free T3, free T4, and total T4 are normal and have been for >10yrs - my endo keeps close tabs on me for Hashi's and an isthmusectomy.

I've learned a lot from reading your site and expect to learn a lot more.
