Another lifesaver for us has been anti-nausea medicine called Zofran aka Ondansetron. We've gotten sick at some point the past three years and it has been a huge lifesaver. Tiff got her doc to prescribe it before we went. There is a pharmacy, though, across the street that sells prescription drugs. I just figured out last year that you don't need a prescription there. Kind of nice! But definitely bring that stuff if you can!
