How long your AFIB recurrency and for how long to return to SR?

Mine is every 9-10 days, for 1-3 hours after 1 tablet of profanenone.
This will be due about the day after tomorrow. I am dreaded as it is getting closer. Don't know what will happen? How severe? Eventhough most of it asymptomatic.

Would love to hear from you, my online Afib Fighter. It may lessen my anxiety.
