So for the last 3 nights in a row I have had palpitations before bed. Have waken up to use the bathroom and had afib for an average of 30 min. I am taking metoprolol, losartan, apixaban, metformin, and sertraline. These occurrences happen exclusively at night and always after eating. No matter what I eat. Has anyone else had this happen to them and if so what was the solution?
