motion sickness
"Went on a 7 day cruise and used the patch, as well replaced it after 3 days.  Worked good for me during the cruise.  Side effects were dry mouth and I just drank a lot of water.  One day I was working out on the cruise and felt like I wanted to throw up. I think its not intended to be used while doing lots of physical activity. Still got to enjoy my cruise with minimal problems.  After the cruise I removed the patch on land and the next day I had severe excruciating headaches.  I didn't feel motion sickness but suffered a huge loss of appetite, I only could eat one piece of bread a day or else I'd throw up. I was dealing with a painful headache/migrane that couldnt subside for an entire 7 days after the cruise.  Warning to all users out there"
