motion sickness
"Took it for 2 day cruise. Put it on in the morning and did not have any problems with motion sickness. I usually get sick in a car if I don't ride in the front and keep looking out. Boat rides are usually bad regardless where I am on the boat. Dry mouth was the only side effect I noticed. My husband started to feel sick at the end of the first day, had him put on a patch and he was fine. Also he insisted he had no motion sickness but as soon as the patch fell off he felt sick again, a new patch fixed that."
