Press a wet newspaper against the center of your forehead.
Who ever consults a medical textbook when they get a case of the hiccups? There must be more methods of curing the hiccups (or at least attempting such) than for any other frustration that ails the human body, and it seems everyone has heard and tried at least one of these folk remedies. I have heard of many supposed hiccup cures myself: scare the person with the hiccups, gulp down water rhythmically (seven times in one particular variant), rub your earlobe with your fingers (this one has actually produced results on me – perhaps there is some real nerve connection there or perhaps it is the placebo effect), drink sugar water, hold your breath.
Recently, my roommate (Lebanese) and I, along with a friend of his from Saudi Arabia (my informant), were driving to buy food, and my roommate began hiccuping quite forcefully. Predictably, everyone began reciting the hiccup-cure ideas they had learned growing up. Since my roommate was driving, he unfortunately had to suffer the hiccups (and did for quite some time) until they passed. I asked the informant how he would cure the hiccups back where he used to live in Arabia, and his method was the most unusual I had ever heard. He said his mother used to soak a newspaper and press it against his forehead. The informant did not know why this worked, but claimed it did. Perhaps the cold, wet sensation triggers a reset button in the nerves and stops the spasms, or again, perhaps it is just the placebo effect – and it is doubtful that any medical guide would ever confirm this for us or would address the effectiveness of these traditional remedies.
