Now, something promising looms on the horizon - Hicural Hiccup Relief.

Now, stopping hiccups is as easy as drinking water. It is basically an extended white toothpick, with a hole in the middle. Stick it between your teeth, and down a glass of water. Apparently, biting on it will tense up the muscles in your throat and stop the spasms in your diaphragm causing your hiccups to be reduced to none.
