Hmmm... good question.

Found this link. More info on hiccups/hiccoughs/singultus than i needed to know. http://www.emedicine.com/emerg/topic252.htm

I knew long time ago that hiccups can be psychosomatic, but what if you're completely happy and preoccupied when they start up? (I just wonder if the nerve thing in my brain that sets mine off is related to the same section of brain that gives me my tachycardia. ...I mean they're both misfiring that set off a muscle spasming at a rate that isn't proper.)

And, yes, sugar DOES work very well.
