I could have wrote what you just did!
I was diagnosed in Novemeber 04 and was started on .50 of synthroid. I had my levels recheched in December (they were ok) and again in March (again ok) but I still felt like crap. I went back to the doctor in July and my TSH was at 15.1. So she started me on .75 of synthroid. I'll go back on August 26th to have my levels tested again. I am feeling a little better after starting the new dose, but I know I still have a long way to go.
I started to supplement with 200 micrograms of Selenium. This is supposed to help with T3 production. I can tell a difference a little.
Ok, I'll type more later! It's time for me to go home!
