If gulping down water can't do the trick, here's another way to stop embarrassing hiccups. Lightly run an ice cube up and down the front of your throat, just right of the center, for 30 seconds. Experts explain that an overfiring vagus nerve can perpetuate hiccups. But chilling the right side of the throat (where the vagus nerve runs closest to the surface) temporarily anesthetizes this nerve and normalizes its functions.
