I am so glad to read all of this information. I am a 40 year old female. I have suffered 2 PEs. I have varied from being on 10 mg of warfarin to 25 mg a day. This is the first time I got to go 1 month between INR checks. I'm on 11 mg/day with INR of 2.1. I am having SEVERE recurrent headaches, sleepless nights, feeling tired all the time, and problems with my memory. Drs tell me they don't know what this is from and there are no side effects to warfarin. I have a vena cava filter in and I'm on the medicine for the rest of my life. Glad to hear I'm not losing my mind (just having horrible side effects regardless of what the doctors say!)
