Have you considered acupressure? If not, your daughter might give it a try. There is a spot on the inside of the wrist, say, 3 finger widths or so from the wrist fold. Feel around for the tendons there and there's a spot in between the tendons. She'll know when she presses on it b/c it'll be a little sore. She can press on it or massage it while doing deep breathing. Tell her to relax and not tense up or grit her teeth while pressing, just to give it a good pressure but not excruciating. It'll just be a sore spot when she hits it. It really does work for morning sickness, motion sickness, all kinds of nausea.
