I use the Bonine as does my teenage daughter. Works great although it can make you a wee bit sleepy. I got so sick on my first cruise (smaller ship), that I was the 1st passenger taken off the ship upon returning at the end of the week and was taken off in a wheelchair! I can hardly believe I actually tried a second time...but I've been on 7 cruises in the last 10 years and love it. Bonine every time for us!
Don't use the neck patch...my experience was not a good one and I tried it on 2 cruises. Too many bad side effects.
