I’m taking 40mg (4x/day) – of the Propranolol – & I thought that was alot. Is there a reason why your’e taking so much – except the obvious one of Graves symptoms? My heart rate is still a little high (95-105) but has come down from 130 – which is good. I wouldn’t be surprised if my Endo adds more mg’s to my prescription. Did you have the RAI or are you on the ATD’s? Just wondering. I know how the dental route can go – it’s no fun. As I’ve posted before, my dental visits have increased quite a bit in the last year and a half. Hope your’e feeling better.
