All I know is that on our last trip to Disney I took dramamine and gave it to dh, dd 11, and my bil 13 at MGM. The day was a big blurr for all of us. It was so bad my eyes were burning horribly I was sooooo tired. We all fell asleep on the boat going over to beaches and cream to eat. I will never ever use that stuff again and it was the less drowsy formula.
