Atrial Fibrillation Support Group

I was diagnosed with A Fib three weeks ago. I had it prior to my diagnosis, but just ignored it because it would only last a short time. I am always tired especially right after an attack. Is that normal? I was prescribed Dilitizem and Pradaxa when I was first diagnosed with A Fib. I am tryin to get a set of appropriate questions to ask my Cardiologist when I see him next week. Thank you.
