Red Rock, if my experience with subclinical/mild Graves is any guide, there are a few ways to approach it. You can just wait and see if it worsens but otherwise do nothing; you can go on a minimal dose of am antithyroid med; or you can on a beta blocker to control your symptoms. I was not a candidate for the latter because my bp is low. I went with the second option, and I did get better in the sense that my hyper symptoms lessened, but it also put me into a hypo state, despite repeated dose reductions. I'm no longer on them, and we're waiting to see if I'm in remission. For the first few months after going off them, I was still mildly hypo, so I started taking a small dose of synthroid. I feel hyper again to dome extent and it's unclear whether I just need to reduce my synthroid dose or if I'm not really in remission. Basically, whatever route you take will require repeated bloodwork. It's been a frustrating journey to say the least.

Do you have a definitive Graves' diagnosis? There are some diagnostics that I don't think you've had that you should arguably talk to your doc about. One is an ultrasound. That helps rule out cancer and nodules. Another is a radioactive uptake scan. For this test, they give you radioactive iodine and then take two different images of your thyroid and measure how much of the iodine the thyroid has used.

Finally, if it is Graves, I would consult with an opthamologist to see if the disease is affecting your eyes. This is another effect of the antibodies present with Graves. They can attack both the thyroid and the eyes.
