Some patients, like yourself, are very prone to PONV, ie postop nausea and vomiting. In cases like that usually, combination therapy is used. It’s at least 3 anti-nausea meds, such as decadron, Zofran, and Reglan, that could be used. Also, perioperative use of a scopolamine patch could be effective. Some studies showed the effectiveness of wrist acupressure. And last but not least is the newest class of medications, so-called NK1 inhibitors, such as Aprepitant showed high effectiveness in late PONV, after ambulatory surgeries, when Pt was discharged home and still is nauseated 48 hours postop.
