Somtimes getting rid of hiccups can be hard. Here is a way that works every time for me:
Or try these:
Swallow something sweet.
A spoonful of sugar is popular because its graininess could slightly irritate the esophagus, causing the phrenic nerves to "reset" themselves, although there is no proof of this.
Try to breathe slowly and deeply into a small paper bag. This increases the carbon dioxide level in the blood and makes the diaphragm contract more deeply to bring in more oxygen, which may stop the spasms.
The paper towel trick.
Place 1 single layer of paper towel over the top of a glass, then drink through the towel. You'll have to "pull" harder with your diaphragm to suck up the water, and concentrated gulping counteracts spasmodic muscle movements.
