I know it sounds nuts, but that hiccup
trick works for me; where you get a tall cup of water, sit it on the table, and drink from the opposite side of the glass. It may have something to do with the way your air passages are as you drink
Also for hiccups, try a spoonful of peanut butter
The only real hiccup cure is one that treats the hiccups for what they really are. Hiccups are caused by the diaphragm spasming. Taking in as much air as possible, makes the lungs expand and push down on the diaphragm. This stretches the diaphragm out to it original position and shape. Hold the breath as long as possible, just don't pass out, and let it out. Voila', no more hiccups. It works every time.
If all of the above dont work.. just watch a horror movie or let something scare U.
