The anti nausea meds didn't work for me. The doctor changed me to a much older one and it worked great. She may need to have saline IV to prevent dehydration. That happened to one of my daughter's friends and they sent a visiting nurse to hook her up.
I learned to keep a small notebook with me for my reactions and questions. It came with me to all of my appointments and phone calls. It's also good to have another person with you for appointments.
