@kjhunt You should be seen by a cardiologist and sent on to an electrophysiologist ASAP. Three years ago would have been great. An EP will, if you're otherwise healthy (enough), offer to perform a catheter ablation to stop the fibrillation. It has a 75% chance of being successful, but repeats are often done when the time comes. AF changes the heart, and not in a good way, so if it still comes and goes for you, it's still paroxysmal and most easily treated. If you are in permanent AF, speak to a cardiologist about options.
