If you suffer from motion sickness, try Bonine for your next trip.  It’s an over the counter drug that prevents motion sickness for adults and children aged 12 and up.  I have found that it works very well and doesn’t have any of the drowsiness I have experienced from other similar drugs, and I tend to react strongly to medications that may cause drowsiness.  I first used it on a cruise where our ship was crashing though 20-foot waves, and I was fine!
