I'm 52 y/o male, started warfarin 6 weeks ago and the last 10-12 days I have noticed a LOT more hair in the tub drain when I shower. Also, my eyesight is getting worse by the day and if I lay down on the couch to watch TV, forget about it...sleeping right away! Had more to say, but can't remember! I do know my neck and back hurt and I am supposed to be on this crap for 2 more months, but I think I am going to pass. My Doctors already love me, so I'm sure this will be the straw...good luck everybody
