Bring both Bonine and Dramamine and experiment with both. Also, if you end up spending a lot of time on the ocean, take heart in the fact that you're supposed to be able to get used to it. They don't call 'em "sea legs" for nothing.

Basically, my problem with Dramamine is that it's a powerful antihistamine which makes me feel dizzy and drowsy, and slows my reaction times so that I feel like I'm moving through life on a 200ms delay. Also it's headache-inducing for me. Overall, Dramamine makes me feel like I have a head cold.

Bonine has no such issues for me because it's a different class of antihistamine. I can take Bonine and feel no side effects.

Dignan, if you're taking any of these drugs as an attempt to combat game-induced motion sickness, make sure to take the drug 30 minutes before playing. That'll give the drug a chance to get past your liver and into your system before you start hitting your body with all that nasty cue-conflict stuff.
