MTGunner: Man I feel for you - that has to be uncomfortable and disruptive for you!
Hope you CAN find a cure (or the cause, then avoid that).
I virtually NEVER get hiccups - I don't know why?
The VarmintWife gets them once every two months or so but they only last 10 to 15 minutes.
Again I hope you can find relief.
Hold into the wind
