Although doctors are in unison that hiccups serve no useful purpose, it cannot be denied that it is distressing having hiccups. The fact that you just suddenly experience hiccupping is already inconvenient; but that you do not know when a hiccup will stop is way more annoying.
Each family employs different ways to stop hiccups, with some of them being strange but funny at the same time. Most people try to drink lots of water, as it is believed that the hiccup was due to eating quickly and that when the person is already at the point of almost choking, he was not able to drink water. Others relieve themselves with the alternating slow and fast breathing, as it is supposed that the hiccup was caused by too much air in the stomach. Also popular way of stopping a hiccup is through bag-breathing, wherein you breathe into a paper bag so as to regulate the air flow in and out of your body. Some people resort to as simple as massaging the back of the throat. Indeed, there are unusual approaches to treating hiccup. It is not enough to drink plenty of water, because what really matters is the manner of drinking, like drinking water while upside down, drinking water from the far side of the glass and drinking a full glass through a paper towel. Others resort to eating particular kind of food, such as taking a teaspoon of vinegar, consuming a teaspoon of honey, eating a spoonful of peanut butter, drinking hot coffee until the hiccup stops.
These medical approaches are merely anecdotal. While most of them are harmless, it is still safe to just wait for the hiccup to stop. Besides, the medical community believes that a hiccup lasts for just a few minutes. Rarely do hiccups last for hours, days or weeks.
