How long can a hiccup last???and where do they come from???
hiccups are an irritation in your diagram... they can last a very long time! the longest recorded im pretty sure is like a day or three somewhere around there. to get rid of them try drinking water, holding your breathe for as long as you can and plug your nose
The world record was Charles Osborne - he had the hiccups for over 68 years and hiccuped an estimated 430 MILLION times!! Source: http://funadvice.com/r/bloh85mm9g4
