In my experience, once those levels get off it can take some time to get them back on track. Now I must also say that I don't HAVE a thyroid so my experience may well not be the norm.

It is hard to be patient with something that makes you tired, or that keeps your heart racing, or...any of the myriad symptoms of thyroid problems. It is good that there is so much information available these days and you are able to take a more proactive role in your treatment. Back in the early 80's when I had out of control Graves there was much less information available.
