Hi Mitch:
I can sort of relate to what you're going through. I was in a similar situation. This post is based solely on my own experience, maybe you can get something out of it.
I am on disability for my UC and Epilepsy. 
I was fighting to keep my job and not go on disability.
I've had UC and epilepsy since 1979.
I'm from Canada and my employer of 30 yrs. has reccomended that I go on Disability (not my choice-fought against it for 4 yrs.and lost) through Sun Life Financial and it has been approved, it kicked in Feb/05. It might have been easier for me to qualify because I also have Ulcerative Colitis.
My employer has put me on medical retirement since Aug./05
I agree that there are a lot of people out there that don't really need it but make up stuff so they can get benefits and not work. I'm only 49 yrs old and I'm not dying (yet)so maybe someone will hire me part time since my UC and EP has been in control (remission) for years.
Did you know that it is a proven fact that epilectics are generally better employees? So employers should be more than willing to hire an epileptic. (unless it's really severe)
They have better attendance because they think they're being watched by their superiors who are expecting them to take lots of sick days.
They work harder and have a better production rate for the same reason. Everyone is just waiting for you to screw up.
But they're still outcasts, Everbody thinks the're different but actually they're more compssionate.
I agree with Hector, Your employer cannot let you go for a seizure condition. It is descrimination (as per the Canadian Human Rights Code)
Your employer is obligated to provide you with the necessary job modifications and/or put you in an area where you will be at no risk to yourself or others.
