Interesting find, I put in Warfarin, hair loss, because my hair is thinning out quite rapidly. It has changed texture (unruly and thin), and it has virtually stopped growing. I am experiencing migraine like headaches which I have not had for 20+ years. I have constant stomach trouble, cold chills in the evening where I cannot warm up (my nose goes freezing cold). I am very fatigued. I do believe my short term memory has also been affected which dramatically. The drug scares me to death (?).
