Are you sea sick?

I want to hear the best remedies for sea sickness: there are many variations on a theme - but what works for one doesn't work for another squeamish sailor. I thought I didn't get seasick at all - but on an overnighter on the Hurtigruten on the North Sea off the Norway coast - mmmm. The little ship was piching like crazy and I knew I was in trouble - I won't go into the gory details but I kept topping up with food so I had something to get rid of - if you get my drift.
So what do you use? Or don't you get seasick?
