Yes: Most of the time they will try to give a variety of medicines during the operation to reduce the risks of this happening. You'll likely get a chance to talk to them preoperatively and this is a very good time to discuss this concern with them and make a plan to try and overcome this problem.

Many options: First, let them know your concern. They can give you a scopolamine patch, give you meds while you are asleep, to a total IV anesthetic and avoid gases to prevent nausea. They can also give you non opioid meds prior to surgery to help with pain so that less opioids will be used. On your end it helps to stay hydrated and avoid using too much opioid medications as they can cause nausea.
