I disagree. The patch can make you feel a little loopy. They advise against drinking while wearing the patch. Go with the $8. wrist bands or Bonine (tablet) Take the bonine for the whole cruise, once a day. You can drink while taking them. Just take the pill in the morning. If you go with the wrist bands, wear them from the time you get on the ship till the time you get off except for when you are in the shower. The earlier you put them on the better, the less you take them off the better.
