I'm not a vegetarian. I eat some chicken and a little fish and the odd bit of pork but I eat vast quantities of leafy greens, mountains of tofu and chick peas and lots of other veggies every day. My diet is quite consistent in that the animals are included in addition to the other stuff. I am also quite active, running, walking or cycling 5 or more days per week. For over one year now I've been stable on a daily dose of 11mg. The Anti-coagulation Clinic where I used to get tested (I self test and dose now) told me that they have a patient taking 20mg/day, and one taking 1/2mg most days, with occacional 1/4 mg doses! I personally notice my INR plummet when I run too much, or when I occasionally overdose myself with spinach. I haven't noticed it with chick peas but that might just be a result of not having tested within a couple of days of eating large quantities of them. Hang in there, you'll likely stabilize soon, then as your activity levels increase further out from surgery, you may need to take even more. Time will tell.
