@predictable Martin, I understand now why you wanted to make sure everyone understood the issues with Vitamin K and Warfarin. Do you have a choice in which blood thinner your doctor prescribes? Would one of the newer ones be a better choice if you forgot to take it once in awhile? Do you monitor your blood pressure too? I'm glad that you are able to talk about your experience and what you learned. My mom's issues with blood clots in her legs are because she can't walk very well and is sedentary in a wheel chair. Her Eloquis is expensive, but it doesn't require the regular blood testing of Warfarin. She's on it as a preventative now.
