My research is showing what you state in the last two paragraphs that generated this comment. I am John and Posted yesterday 10/16 in Medical Information Forum Section. My TSH is 18. I feel great and generally do not have symptoms (see my posting) but I see signs in my blood test that are gentle warning signs. I started Syntroid yesterday 25 mcg.....But I will work with my Dr on what my specific "tag disorder" is. Lets say it is Hashimotos(sp?)I will add the correct natural supplements to help the situation, monitor and adjust. Incidently my first dose of Syntroid @5:00AM today. It was like a caffine shot. Was a chatter box at work for a few hours.
