Met with my consulant who has diagnosed APS. Started warfarin therapy last Tuesday.... 10mg for first 3days.. My inr started at 1.2 and has gone to 2.2 already.. My warfarin is now 3mg daily... !! I've been to hospital each morning to have bloods taken for one week and returning each evening for results and medications... My target is between 2 and 3... Has anyone felt really tired after starting warfarin as I would normally be getting around 7 hours sleep I'm now sleeping around 12.... And still feel tired when I get up!!!
