Hi Monte,
Firstly, there is no such thing as a stupid question if you dont know the answer. Secondly, I have to be honest and say that I really dont know about this one. Its not something that I have heard of before. As far as I am aware, the imbalance of pressure either side of the diaphragm causes hiccups (And its possibly the pressure which causes the stimulation). I dont think its seizures but then im not a doctor.
