Kind of funny I forgot one of my main complaints of this drug, but it is the forgetfulness. My mind is not as sharp as it used to be, sometimes I feel like I am in a fog. My recall can be really bad, too. Someone can ask me a simple question and I draw a blank. My dad was on this stuff for years, he has since passed, but he had the same memory problems, although no one ever thought it was from Warfarin, but now I wonder.
