Hi Nick,
I have had the same exact thing happen to me. Did you ever find out what was going on? I am getting greatly concerned. Two weekends ago, I passed out in the bathroom of a book store. Twice last night I almost passed out. How you described what was going on with you is exactly what is going on with me. I cough and half the time I can just stop. I go into a fit. I may not get dizzy with every cough but I do with at least 50% of them. I get the rush of pressure to my head also.
NJC...what is a vagal reflex?
Thanks a lot

It is not so rare to have this occur with violent coughing episodes. It is more like a "vagal reflex" than a hyperventilation episode. If you are experiencing this type of reaction, I would suggest speaking with your physician about this.
