Ok, here it is the perfect cure for hic up's. It works every time for me and all my freinds for the last 30 years or so.
Take a glass of water and get a pencil/pen and put it in your mouth, drink the glass of water without stopping while trying to breath at the same time.
If you do this correctly your hic ups will be gone. If you say it doesn't work you haven't tried it properly.
This is a family secret that I am passing on to you. It works every time.
Stan.
