This informant is a sophomore student at USC. I explained all the different types of folklore there were and he decided to share his his recipe for getting rid of the hiccups that his mother swore by.
First you eat a lot of grapes, like 6-8 until your mouth is pretty full. Then chew them up and swallow them quickly followed by a big glass of water. After the water goes down, hold your breath for as long as possible and only let out small amounts of air at a time. Finally when you absolutely have to, take a deep breath and your hiccups will be gone!
I really didn’t even know what to make of this hiccups remedy, the grapes seem to be completely out of left field. However, I have heard before that holding your breath can help.
