Glad you are taking the ginger capsules. They are effective and have the fewest side effects.
I usually take Bonine. It works well for me and does not make me sleepy. Dramamine knocks me out.
Different medications work differently on different folks, though, so you might want to give these a try before you leave... pick a day when you're not going anywhere and take one or the other, and see how it affects you. If you don't like the side effects, then on a different day when you're not going anywhere, try the other one and see about it.
