I have to say that, in my experience, there are two main factors with regards to seasickness: mental and physical
My OH suffers with seasickness but I am sure one of the main reasons she does is the fact that as soon as anyone mentions a boat, she thinks about seasickness. She does have a slightly higher physical tendency to motion sickness with regards to flying etc though so it is not all in the mind.
I have only ever suffered once and that was my first time diving off a day boat. I made the mistake of gearing up during the transit time rather than being ready to dive as soon as I was on board. Done two weeks of live on boards since with some dicy conditions (boat rolling in three dimensions by about 20-25 deg due to three currents meeting) with no issues. One thing that helps me (as mentioned above) is the mental image - I can see the image in my mind of exactly what the boat is doing.
Another thing to do is watch your food and drink - eating something like dry toast (no butter) will help to stop stomach juices sloshing about while making sure you don't drink anything too strong can help. Ginger can help with sickness so a ginger beer might not be a bad thing (or Irn Bru if in Scotland!).
