Sounds like you are on the right track to me. There have been a lot of threads on seizures here. You might want to do a "search" because there are some excellent websites that have been mentioned. I know what you mean by the Rx problems, and if you can get him off them all the better. Your food research also sounds first rate. Let us know how everything progresses. My Austin has seizures, but is not on meds. Even thunderstorms can get him off on a seizure.
