INR High for no reason

Things have been pretty stable for a while now.  Just the odd subtle dose change to handle a trending high or low.

Suddenly, for no reason, a test came back at 3.8.  And I mean no reason.  I felt fine, diet was normal, exercise was normal.

I adjusted the dose to cope with it a little, ate lots of green food, and problem went away.  This was the first in a number of lessons that warfarin is not a stable drug. It can just change on a whim.  If I hadn't been self testing - presumably it would have just gone high... perhaps come down on its own after a while.  Hopefully i would have avoided any major problems, but who knows.  One bit of bad luck, as sods law often dishes out, and I would have had a big problem.
