I had a lot of trouble with A Fib for 2 1/2 years. May 21, I started mixing 1 tbsp of diatomaceous earth with water or yogurt or protein drink. 6 months later Nov 21/16 I still have not had another attack.
Prior to that I used lots of magnesium and tried valerian and cayenne but got no help from these. I urge anyone with this problem to try this method. You have nothing to lose. Very inexpensive and helps with other issues too.
