Rain,
Two years without any real problems - you are doing things right. Actually I think you are a good example of what I try to teach people. A little high, a little low, no big deal - make a small adjustment and get on with life. If you have a choice, be off a little on the high side - it is easier to stop a bloody nose than to put in a new valve. A few little red spots - so what! By consistent, I don't mean boring. What I mean is that I have never seen even one homeless person who could take warfarin for more than a month. There is so much inconsistency in their lives that they can never get a medication routine established. Warfarin is a factor in your life, not the ruler.
