I was 8 years old and my family rarely drank soda. I went from having a diet coke occasionally to occasionally having a regular coke, ginger ale, root beer, etc... So I don't recollect changing my periodic intake of caffeine.

I didn't do a thorough study of it... and I recognize that the logic that aspartame was a trigger could be wrong. But when you find something that appears to work and later hear of others who identified the same potential trigger and fix, then you start to believe it may be true. Personally I don't think there have been sufficient studies to show a connection or not. But people who have seizures shouldn't rule it out.
