Some folks do well on Coumadin, others can not tolerate it. If you are afraid of Coumadin, but want something that will help thin the blood, I would suggest the herb "Ginger" this can be purchased in pill form
, and it has the same blood thinning properties as aspirin WITHOUT the side effects. Since it appears your A-Fib is not constant I think I would go this route first, oh yes, also, a good, liquid
fish oil would keep the blood slippery and clot free.
