That's too bad that your Afib has taken this turn. I have said this before and I will say it again; cut out ALL stimulants such as coffee (not even 1 cup), tea, alcohol, stress, chocolate, dental medications etc.. When I had Afib (I cured myself of the worst case the cardiologist had ever seen) I was told not to EVER have those stimulants again in my life....and I listened. That could certainly help you BIG TIME! Good luck!
