Hey! We are the friends of Monstro from GA. This is our 6th DIS cruise. We have taken motion sickness tablets with us each trip, but have never had to use them. The boat is so big the movements are small. It will give you sea legs for a few days though.
The original Dramamine is good, but it can cause drowsiness. It is closely related to Benadryl. Meclizine is a better medication. It is less sedating. It is sold under the names Bonine, Antivert, and Dramamine Less Drowsy Formula. The thing to remember is that meclizine is a lot better at preventing motion sickness than it is at treating the symptoms. Usually you take one dose an hour before you start the activity. It can last for 12 to 24 hours. After that you just take it once a day. It is OTC. You should be able to get it in a chewable and a liquid. I have bought both at Wal-Mart.
