Hi guys...my dynamic has changed last 2 weeks never used to have a problem sleeping. Im on 1.25 bisoporol and flecainide x 2 100 mg. I exercise during the day and cope well with few symptoms during day. As soon as i lie down to sleep my af kicks in. I prop myself up with a few pillows which helps slightly but there seems to be a correlation with lying down or is it anxiety because im not sleeping ... i know your heart works harder when you lie down. Any one else experience this.
