Omg Labs!!! Trying to Understand!

Posted on a few thyroid boards last night to get some guidance around my labs. I clearly have some more learning to do about labs! I thought I was more hyper because my TSH went down, but come to find out that since my T4 Free went down slightly that is actually a sign that my thyroid is slowing. At this point its hard to tell if it starting to slow because of the RAI treatment or because I was still taking my Methimazole, which I stopped taking last night. So I guess my next set of labs in two months will really determine what my thyroid is starting to do. My assumption would be is that docs start/determine your Synthroid dosage based on your T4 Free and not necessarily your TSH since technically Synthroid is a synthetic T4. I will have to do more research on my assumption. 
I thought it would be interesting to share my labs since being diagnosed with Graves. I do have some missing labs that I never obtained from the doctors!
