For the last year I've been taking Warfarin, an anticoagulant. It's part of my daily medical regimen and I have never hated a medication more. It doesn't taste bad and apart from easily bumping and bruising there are no serious side effects.
The worst thing about Warfarin is that vitamin K is a coagulant, which means it's off-limits. Vitamin K is in nearly all green-leafy vegetables: lettuce, spinach, cabbage, and my beloved broccoli. It is also in cranberries and avacadoes.
For some reason my Warfarin level refuses to go up, I've been at 1.4 for months now and if it would go up, I would be allowed a little bit of my favorite vegetable, and maybe a dill pickle now and then.
