Can anyone on here please tell me how long you have to take warfarin with a count of 1.6 week after week month after month, before something else is done (apart from upping warfarin), to get you in range. If for any reason you never come into range, what happens then???? Someone put me out of my misery. My nurse told me perhaps the glass of red wine and soda I drank every night for years (not since I on warfarin) that is missing, but it scares me to death to start again but I woud love a glass of wine and soda, but is it too late now? to start again after so long.
