I use the SeaBands and Bonine too. First, I wear the SeaBands and then if it is really rough I take a Bonine. On this last cruise, the only problem I had was during one of my workouts. I forgot to wear the SeaBands and soon discovered that I get seasick walking on a treadmill looking at the rough water going by. I headed for my suite, took a Bonine and an hour's rest. All was well.
