11:30 AM: Quick update. Sophie has been vomiting this morning, and she lost consciousness after the second time. I called the doctor, and they said to take her to the local ER. Randall is there with her now (I came home to pack an overnight bag, just in case). They are running some blood tests and plan to send her to Chapel Hill by ambulance, just in case there's a problem on the way there. They will do some brain scans--one of the rare side effects of the methotrexate she took yesterday is seizures. They suspect she'll be coming home tonight, but we want to be prepared to stay just in case. Elisabeth is staying with friends from the church.
