Placed on flec 50x2 12/2015. No episodes for one year. Gall bladder removal 10/28. Then note afib episodes every six weeks. 2/3 had a uti, stomach virus and dehydration. Afib episodes everyday forv3 days, had to take 300 mgs to get back in nsr. Cardiologist feels flec isn't working, but it's still helping me. Has anyone experienced this, so far 7 days in nsr taking 100x2.
