There may be no other hiccup remedy that is more popular than drinking plenty of water. Usually in my case, I get a hiccup after putting too much food into my mouth, and I failed to drink water while on the verge of choking. What I always do is to drink plenty of water until the hiccup stops. So far, this remedy has not failed me. However, I learned that hiccup under normal circumstance just stops after a few minutes notwithstanding any medical intervention. Drinking water may not have any curing effect at all. Probably, like most hiccups, mine has resolved on its own.
Regardless of the unreliability of many hiccup remedies, people have not stopped formulating more anecdotal medical approaches to hiccups. In fact, some people have gone so strange with their approach on curing hiccups. For example, there are others who have superstitious restrictions: 1) Drink water at the wrong side of a glass, drinking water while upside down; 2) drink a full glass using paper towel; 3) Put a knife in a half-filled glass of water and drink all the water leaving the knife in place; 4) While holding a thin object, such as a pencil, chopstick, or straw between your lips, drink a tall cold glass of water; and 5) Turn your left wrist clockwise until your palm is facing outward; from that position, pick up a glass of water and take three sips over your wrist.
While others rely on folklore, there are those who opt to be very calculating with their water drinking method. They like to be particular with the amount of water to take. Examples of these are: 1) Hold your breath for ten seconds; then, without taking another breath, drink water for ten more seconds; 2) Take three slow, deep breaths; hold the third breath while drinking a big glass of water through a paper towel for as long as you can or until the glass is empty; 3) Take eight sips of cool water without breathing; on the ninth sip take a deep breath from the diaphragm, and let it out slowly; wait a few seconds; repeat if necessary.
Identifying the causes of hiccups is the most essential, especially with chronic hiccups. More often than not, hiccups that last for several hours, days or weeks have close association with serious illnesses. Hence, the abovementioned remedies may not be safe to employ to chronic hiccups.
