Doctors have been left baffled by a teenager, who has hiccuped an average of 25 times a minute since November 20.
Chris McKernan, 19, of Tunbridge Wells, Kent, has hiccupped an average of 1,500 times an hour - meaning he's awake around 16 hours a day, and hiccuping 24,000 times daily, the Mirror reported.
When calculated the figure comes to an astonishing 1.4m times.
The accounts manager said that he has gotten "sick and tired" of hiccupping and has tried "every trick in the book" from sucking a lemon, standing on head to drinking water upside down.
