motion sickness
"This is by far the best thing on the market for motion sickness. My husbands first love is the ocean so I have had to find something that helps me function on the water.  I take it the night before and only have to take 1/2 the morning of our crossing to Catalina.  It really works.  A sail boater told me about this medicine 20 years ago. The only problem, it's hard to find.  More people should know about this medicine."
