atrial fibrillation
"Had an irregular heartbeat a month ago.  Not a rapid heartbeat but several normal beats follwed every 30 seconds or so with several faster heartbeats. This would repeat again. Dr. diagnosed me with A-fib.  Placed me on Propafenone 150 Mg 3x a day.  Have not had another episode but the medicine makes me very sleepy in the afternoon.  Hopefully my body will adapt and this will go away.  Has anyone else had the same side effect?  Would appreciate a reply."
