We swear by the pill version of the scopolomine patch calle Scopace. My wife has had severe motion sickness issues for years until we discovered Scopace. It is available by prescription only. What we like about it is that it does not make you sleepy or spacey. Just get a little dry mouth. Also you take it when you need it. Each tablet lasts about 8 hours. If you are on shore you don't need to take it. Then, take one about an hour before your ship leaves port. You can get more information by a web inquiry under "Scopace".
