I am glad that all those lifestyle changes have worked for you. As I said in my comments, I did all of that too; I lost weight, gave up all alcohol and switched to limited amounts of decaf coffee. I never drank any sugary sodas or ate super salty, heavy meals. I exercise every single day. But when we were grounded in France after my husband's injury, I drank regular coffee because that was all that was available, drank an occasional glass of wine because it was so stressful, ate chocolate in their sweet rolls because it was one of the decent things available to eat. I walked miles in hot weather, drank water like a camel because it was so dry and had many sleepless nights due to concerns over his condition and our situation--and I never missed a beat! I am convinced that there are "triggers" but that is not all there is to it; everyone is different and episodes are sometimes unexplainable! I admire your efforts and I am glad it works for you, but I would hate to have all those folks out there that think these changes will be the "cure" for their A-fib to be disappointed if they still have attacks of arrhythmia. My electrophysiologist calls it a crapshoot; all those changes may seem to work, but breakthroughs are often unexplained by any causal event/behavior. Good luck; I hope you stay well!
