@lindy9, forgive me for my direct response: Over the last 15 years with my sterling medical team, I probably read a lot more about my conditions, symptoms, treatments, medication, and prospects than you'd suspect. I worry that your recommendations will be taken seriously by others who don't have top drawer medical care, risking more than they should. I'll continue to take the advice of my medical team (which has helped me reach my 90th birthday this year) rather than the contrivances of the American food processing industry reflected in their advertising and in the ravings of federal politicians.

If Coumadin is Warfarin, that's the 1st medication I was prescribed ... 2 months after my G.P. diagnosed A-Fib & prescribed Warfarin my Daughter & 2 other friends said to me, "What Did your Dr. Put You ON? You Aren't Yourself ... you've become Very Negative, you don't even Look like yourself, very 'drawn & grumpy'." (Didn't want to admit to myself, I was sleeping a restless 4-5 hr.s per night, had shooting pains in my arms & legs, & felt like I was living in Slo-Motion". Finally 4 months after being put on Coumadin my Cardiologist called the G.P. who'd prescribed it & asked him if he was aware of what it was doing to me, She Felt I should be taken OFF it, it appeared to be doing more damage than good.
Short end of the story, I left that G.P. The cardiologist tried Eliquis & 4 other blood thinners ... All caused side effects that the Pharmaceutical-Patient instruction sheets instructed "See Your Dr. As Soon As Possible if you are having any of these Side Effects". Finally the cardiologist resigned herself that the Only Thing I was going to be able to tolerate was Low Dose Aspirin.
She ordered a battery of 12 or 14 tests, came back & said the tests indicated I have a .03-.06% chance of having a stroke. If A-Fib isn't bothering me, If 98% of the time I don't even know I have A-Fib, "You're One Of The Lucky Ones!"
