I think you are an example of how everyone is so different in this A-fib experience. I made all the dietary changes that you mentioned (well, with modifications); drink only 1/2 caf coffee, no alcohol, no sodas, rarely touch chocolate, no desserts, no heavy salty meals, eating lots water to stay hydrated, etc. I had three episodes of A-fib in May. Then in June when we were stranded in France for 30 days due to my husband's accident, I wasn't able to stay dietarily strict due to limited choices--like no decaf available. In spite of all the stress of the situation, and the change in diet, I had not a single erratic rhythm. I am not saying that diet doesn't matter but I don't that is a cure all for many folks. As my electrophysiologist said, identifying
"triggers" are often a crapshoot. I just wish you the best since I appreciate your frustration with this.
