I had an ablation December 2014 with good effect only had one minor episode of AF in August. I haven't been feeling great recently, felt agitated and shaky and last night pulse started to race at about 100 and was normal rhythm until this morning when I feel AF kicked in. Still feel some slight irregularity but don't know whether to ride it out and hope it goes of its own accord or take the fleicanide I've been given as pill in the pocket. I was not really given any guidelines by my EP on how much to take and when. On the tablet container it says take 2 100mgs tablets of fleicanide when required. I am on 5mgs bisoprolol and warfarin. I notice some people on this forum take 1 tablet then if it's not effective another one a few hours later. I would appreciate any advice from people that use it as a pill in the pocket.
