Often times, persons with Epilepsy discover triggers to their seizures. Triggers vary from person to person and please keep this in mind as mine is from personal experience. I advise keeping a diary of what was going on, food, time of day, etc. This will help you discover what you need to avoid and also help your neurologist in determining your ongoing treatment.
