15 years. Dose the diet, don’t try to diet the dose. If you eat greens and a salad 3x a week keep doing it. The dose will be titrations to match. It simple and I haven’t had a problem.
I get my health care from the VA. I’ve been on warfarin for five years and they’ve always told me not to adjust my vitamin K intake. Rather they have altered my dosage to work with my vitamin K level.
My father was on a blood thinner.
It was really annoying to him since he really liked to eat, especially green onions, cabbage, etc.
I think he was on for maybe 30 years, until his death in his latter 80s. A stroke sent him downhill fast.
