Thank you so much for this site... I thought I was alone and loosing my mind. I started on Coumadin in Dec 2008... after 3 months I am falling apart... I can't seem to get anyone to listen... I am tired and cranky, gaining weight faster than I can keep up... I have dizzy spells and headaches, nose bleeds and just an overall feeling of not being me... like said above me... I miss me. The symptoms are so similar to being depressed its hard to pull yourself out... its hard to explain to other people how you are feeling because your doctor continues to tell you it is all in your head... I am a mess.
