Go to Mexico!!!
A little "Montezuma's Revenge" + scuba diving off a dingy in Playa del Carmen's choppy waters with strong current = everything inside of you will come outside!
Remember that scene in Stand By Me where the kid throws up after the pie-eating contest, starting a barf-o-rama of everyone throwing up all over? Yeah, that basically happened in Mexico on our dive boat. We like to call it "feeding the fish."
