I don't know if this will help, but they make wrist bands for people who get nauseous on boats, car trips etc. and I know several pregnant women who use them for morning sickness. They can be purchased at boat stores, drug stores etc. They are called wrist bands for nausea and they seem to work for all of the above but I don't know if anyone has tried them for pd nausea from meds. Cost is about $15.00. Den
