I have started taking about 50 mg of tryptophan before bed and I sleep great. I don't know why it works so well in my case for afib!!!! Might be worth a try. I am using a pretty low dose. I've had afib since I was 3 years old. I agree that taurine is good too. But that didn't actually stop my afib. Tryptophan completely stops it within an hour!!!!

Hope this helps someone!
