Why does a spoonful of sugar stop hiccups?

just curious why it worksWhy does a spoonful of sugar stop hiccups?
Holding your breath for as long as you can usually works, followed by swallowing :) It is supposed to stop the spasms of the diaphragm
[ref: http://www.byedr.com/medicine/141-byedr-... ]
Sugar is nominated on this list of hiccdups remedies, that be new to me so gratitude for sharing that one - you learn something topical everyday :) [same ref above]
This has be suggested as a home remedy:
"Hold your breath.
Drink a glass of sea quickly.
Become frightened.
Use smelling salt.
Pull hard on your tongue.
Place one-half teaspoon of dry sugar on the wager on of your tongue. (You can repeat this process 3 times at 2-minute intervals. Use corn syrup, not sugar, in young-looking children.) "

Quoted form the same source:
" The plea that these remedies are thought to work is that carbon dioxide build-up in the blood will stop hiccups, which is what happen when you hold your breath. If the vagus nerve that runs from the brain to the stomach is stimulated, hiccups can also be alleviated (this is what is stirring when you drink water or verbs on your tongue)."
