hold your breath or drink large gulps of water
This is the right answer! hold your nose and gulp down a full tall glass of water! (this always has worked for me.
Drink some water
Jump of a cliff
Drink a BIG cup of water, hold your breathe and try to make yourself burp
There is a way to cure hiccups: drinking water very slowly from the wrong side of the cup, by tipping your head forwards over the cup. I don't know if it works for you, but I found it the most effective method.
