Look, I will have harsh words here so nobody flame me please. I get motion sickness fairly easily. I have gone on two cruises now, and prior to leaving I call my family doctor and she has both times prescribed the patch for me. My co pay is about 10 dollars. It comes in a box with 4 patches, each one being good for about 2.5 days. I put it on before leaving for the plane. I have never had a problem at all. The first 10 minutes I get a teeny bit dizzy. Suffer through that and you will be fine. Both cruises I have had a few bad times when the boats were rocking. You can't always go somewhere and watch the horizon. I would NEVER consider going on a cruise without taking the patch. God knows, if I am already throwing up, there is no way I can take a pill and keep it down. PLEASE JUST GET THE PATCH IF YOU ARE WORRIED. The cruise is too much money to ruin not only your time, but hamper your family.
