Hi,
You might be interested to know that what you describe is called sub clinical
hypothyroidism and has been recognized by the American Association of
Clinical Endocrinologists. You can read up on this at their website:
www.aace.com/guidelines
(note* the site is sponsered by the Synthroid mfg.)
BUT the site does have excellent info.
Also, try: http://thyroid.miningco.com
Good Luck,
