*WARNING*
I am not trying to practice medicine!

I used to get terribly seasick as a teenager fishing with my dad out of Westport, so much so that I avoided saltwater for a number years. I tried scopolamine patches some years back with varying degrees of success. I didn't hurl, but if you wear a patch for a couple of days in a row, you might have a problem with double-vision and I promise you won't be able to work up enough saliva to spit! Scopolamine really dries you out. A seaman friend that crews for Foss is some of the worst conditions you can imagine passed along this tip and it works great for me. If I'm headed for big water, I start taking meclizine 2-3 days before my trip. One tablet in the morning is all there is to it. You probably know this by it's brand name Bonine or Bonamine. Ask you r pharmacist for the genaric (meclizine) and you'll get 5 times as many tablets for roughly the same price.
Another thought is talk to your doctor about compazine. I've read that they give it to the shuttle astronauts for nausea. Available by perscription only.
These techniques work not only for myself but for my wife. They have been put to the test In the Queen Charlottes, 50 miles out of Westport for albacore, 25 miles out of Tofino for kings and halibut.

Try giving your doctor a call, there are remedies available that don't involve bacon grease, anchovies and beer!
