The less drowsy dramamine is the same as the bonine (exact same ingredients - 25mg Meclazine). It also claims to work for 24 hours. So when I have been on my cruises, I take it at bedtime so I'm going to sleep anyway, and I'm fine during the day - no seasickness. I'm going to try it next month in Disney. I still don't think I will try Mission Space. I hate those simulator rides. I got sooooo sick on Back to the Future at Universal even with my eyes closed. But, I would like to try riding the teacups again.
