@JAMOS...Are you experiencing bloating/gas rather than nausea? The cisplatin is usually administered with some long-lasting anti-nausea meds during the infusion along with a prescription to be filled for other anti-nausea meds to be used at home as needed. Bloating/gas is a different matter and apparently not everyone experiences it. What we found helped with bloating/gas is simethicone (CVS Pharmacy has a higher dose in their brand)...along with a dose of milk-of-magnesia. Hope you find some relief soon.
