Does anyone else taking Warfarin eat a lot of dark green veg. Cabbage etc. I do eat these most days . Doctor says if I eat less one week or more than usual the next week it can disrupt the medication. Then I will have to go for a blood test because of the Vitamin K in these veg. I am going to buy something that I can use at home when I understand the condition more. I am still quite new to AF and the people on here always give me good advice.
