Mike,

You should look into the wristbands that have the little ball on them for the stomache problems. Surpisingly they were very well! West Marine has them but you can get them from drug stores too. ( http://www.westmarine.com/webapp/wcs/sto...productId=31927 )

My son and I used them with great results out at Neah Bay this summer. I don't usually have a problem unless I don't get enough sleep. But on this day he was having problems and and I started to get a bit queezy too. 10 minutes after putting the bands on I felt fine and he was much better. We didn't go in but did find a place we could see the rocks and was fairly calm.
