I'm a 65 year old female. I have a moderate aortic and a mild mitral valves insufficiency.In November I had an episode of AFib and was put on Tikosyn, 500. I'd like to drop this medication because I am limited to take other medications (it has too many contradictions). What is a save way to do it (now I'm taking only one capsul by my own initiative), and what are medications that are not so strong, but still can help me live without AFib? Thank you. Nell
