I just wanted people to know that like many others, I used the scop patch for my cruise last week. All was well until the 4th day when I woke up to complete blurry vision and HUGE dilated pupils. Fortunately I had the insert with me and found out that this is one of the less common adverse reactions. It was terrifying though and took at least a full 36 hours for this effect to wear off. I think people are better off with the Bonine.
