Thank you for both of your responses. I am still feeling jittery – but have been put on some anti-anxiety meds that seem to be helping a great deal. Today was one of the first days in a long time I have felt virtually jitter free. I know that this is a slow process, and just trying to take it one day at a time. Saw my endo today and she put me back on 136mcg of Levo, with a check back and blood draw in a month. She said that GD is so uniquely personal – people can have lots of different symptoms, and some that can be confusing. I have been taking yoga 1-2 times a week and always feel better after. Thanks for listening – it is very helpful to know that others are out there going through the same thing.
