Drinking tea every morning (whatever the color) seems to be an easy thing to do consistently. (Not a tea guy myself, but my coffee consumption doesn't change much.)
There's a theory out there -- and I've seen some evidence that supports it at least weakly -- that it's easier to keep your INR consistent if you DO eat some foods that contain Vit. K, than if you eat NONE. Of course, you either have to have some consistency to it, or you have to monitor your INR reasonably frequently.
