I had my sleeve yesterday morning (6/4/19) and I have had zero nausea! I just wanted to share what my doc gave to head off post-op nausea. I put on a Scopolamine patch the night before surgery and then took an Emend on the way to the hospital for surgery. I truly believe these two things kept me from being nauseous. I know if insurance doesn't cover the Emend it can be pretty pricey. I say it is worth every penny!
