I gave up smoking two years ago and since then my AF episodes, rather than easing as I expected, they have increased and become different in nature. I was a bit cobcerned about this as the episodes became daily and I was loosing sleep over it.
So I started to change my diet to try and isolate the culprit or culprits. The one thing that I had changed was eating my eating habits. I chewed a lot of gum and ate more putting on weight.
This is what I have found and this worked for me as I have reduced the amount and severity of my episodes to a managable level.
BAD ..... Chocolate, Aspartaine (artificial sweetner), Caffiene ( in anything!), ice cream in quantity any flavour.
Not as bad...... Cheese, white bread.
I am still trying to find others. Let you know as I do.
