motion sickness
"I highly recommend it. My husband & I used it on a cruise to Alaska & the waters leaving out of Seattle got pretty rough, we literally were holding on to the walls walking down  the hallway. With the bad waves the 1st day I felt a little queasy but I did not get sick. There were couples that it was their 3rd & 4th cruise to Alaska that said the waves were the worst ever & they were sick.... Should have used Transderm. I will never cruise again without it!"
