At school, this guy in my class was hiccuping for three days straight and at one point stopped breathing, so he went to a doctor about it. Doctor told him to run for ten minutes on the treadmill, and he was fine. Apparently during some shouting argument he'd pushed his diaphragm out of place and that's what caused it, but the heavy breathing of exercise put it back into place or something.

So yeah, run on the spot or something.
