that altogether sucks.
I am just telling you my not so horrible story of coumadin which I have been on since april, I have over anticoagulated and underanticoagulated, but eventually got the dosage right. Mostly I eat green 2-3 times a week, and did that so that the dosage would be set to that, then I ate too many veggies and dropped to 1.34, then they upped the coumadin to compensate for the veggies, etc. etc. I still cut myself frequently, you know, grating something, or pulling something open, but they coagulate anyway, even if it is slower than usual.
the bracelet is a really good idea.
I still don't cycle or run from the hip fracture (hope to start next week though), and only swim, so cannot help you on that one.
I hope I don't have to anticoagulate the rest of my life, cause I would like to get pregnant! (like is an understatement here)
