I recommend the Meclizine too. I suffer from Vertigo from time to time. I get basically the same feeling you get from being on the ocean, sometimes on the verge of puking. I have a prescription of Meclizine to take when it gets bad. It works great. Only downside is it makes you tired. Talk to your Doctor about it.

I have to admit though that when I fish in Baja I find a couple of Pacificos on the way out keeps the sea sickness away.
