Yes, be totally honest with the doctor or nurses who are caring for you and they will do everything they can to help you and make you feel okay. They can definitely give you an anti emetic...and you can also ask what type of anesthesia they are using. If its' propofol (the drug Michael Jackson used), that has anti emetic properties in it and it wears off fairly quickly too. And not eating isn't going to help you...you need your strength and immunity kept up!!! Eat small but healthy and frequently. Good luck and hugs...
