Hello, My mother is 80, type 2, overweight, chain smokes, Parkinsons, 26 medications daily with pain meds and anti depressant. She has had nausea every afternoon for a week (too many meds to pin down a culprit, but anti-nausea is one and not working apparently). Today she has tar stools and doesn t want to eat. The DNR is on the refrigerator, she refuses to go to doctor. As her daughter/caregiver, having even a remote idea of problem, how to make comfortable and be prepared would be appreciated. Thank You
