I am on Coumadin. If I am to eat "good foods" than I have to seat the same thing,same amount, at the same time every day. That gets old, so I have cut out the Vit K foods to keep the amount of med low, so I don't bleed out from a paper cut. I will have to wait until I get of the meds (if ever), I have quite caffene usage (about a month ago) but I think that is about as good as it gets for diet alterations for me for a while. Bummer.
