Theo, you said your interesetd in reading some proof on  allergies
causing szs.Here's one site,  

http://www.edelsoncenter.com/Diseases_Treatment/epilepsy.htm

Also if you want more proof you can get a book called "Brain Allergies"
by Dr.William Philpott.

Just my living side of it, Wheat was a major sz trigger for me, but
after giving it up for a few yrs I now can eat it w/out seizing, I gave
up alot of foods to be in control of my health today, If you haven't
yet, get yourself tested to see if its more than one allergy you have.
Hope this helps you now.

Sincerely
Kathy
