I get motion sickness pretty easy. In fact, we didn't start cruising until 18 years after we were married out of fear I'd be sick...so much wasted time!
My first cruise I had the wrist bands (which in the past did nothing for me), and Bonine. I felt a little off once or twice (on a Carnival Fantasy class ship). Looking back it may have been the bonine. Also the bonine made me VERY drowsy.
My mom (where I get my motion sickness from) uses the scoplamine and still has some effects.
After that cruise, I kept it with me, but have been taking ginger pills. I usually start the day before and take two a day. I was able to take several tender rides (including Belize which is a ways from the port), and an excursion around Half-Moon Cay with a boat ride, snorkeling and back with no ill effects. We had a forward cabin so in theory I should have felt all the waves etc... but didn't phase me at all.
Since starting with the ginger pills, the only time I recall not feeling well was on an RCI ship where the dining room was right above the engine area and there was a constant vibration that didn't sit well with me.
You've taken your cruise by now and hopefully had no ill effects, but went ahead and replied in case other see this.
