The traditional home remedies will suggest that you breathe slowly
and repeatedly into a paper bag, or just eat a piece of bread.
Here is a technique you never heard of before: gently massage your temples,
those soft spots to the outside of your eyebrows on the sides of your head,
while at the same time repeating the word "Rumplestiltskin."
This is much the same technique as stifling an unwanted sneeze by
gently pressing the upper lip, just below your nostrils.
This will interrupt the nerve spasm that is causing the hiccup which
usually started when you swallowed air too quickly.
It is better to do this when you don't have an audience.
If it doesn't work for you, then you will just have to wait
until the spasms subside.
