Hiccups are psychological. just think that you don't have them and they'll go away.
this is my cure and it has never failed me or my friends ever!take some water and hold it in your mouth, now do a hand stand (not for long even if its just 1 second)no come back down, stand up straight and swallow the water in your mouth.never fails.
