what was the root cause of hyperthyroidism?
Grave's disease, thyroiditis, toxic adenoma?
Please post the actual results of your thyroid blood work. Include reference ranges as they vary lab to lab and have to come from your own lab report.
Are you having any hypo symptoms?
I agree with you. I'm on a beta blocker, too, and everything I've read says you wean off of them. I'd want to take that slowly.
