Fairwinds, by all means give it a try. Sometimes you can get your body acclimated to the sea, and find it gets easier every time out.
But there's also a wealth of solid information on beating it.
Alcohol or smoking within 24 hours will make you more likely to be sick, as will exhaust
fumes, especially diesel
. Anything that reduces blood oxygen levels as well. Insufficient sleep, excess heat and humidity, or low bpdy temperature from being cold or not having eaten recently. Greasy foods--skip the clam chowder and anything with lots of dairy or fat as well.
On meds, there's something that works really well for almost everyone, but nothing works really well for more than 1/3 of the people who try it. Compazine, Sturgeron, Scopolamine (my choice) are among the meds that hit hardest. All have some side effects and sometimes bad reactions, so the best thing is to try them AT HOME on a slow weekend, so you can either get help or sleep it off or, more typically, decide if the drug has any odd effects on you like cotton mouth. Then when you try them at sea, you don't have to worry about imaging things--you already know what the drug really is doing.
There's also the wrist bands, ether the plain elastic with a button on your wrist to stimulate the ne-qwan point (works somewhat) or the electric
Relief Band, which is so effective it is used for morning sickness and chemotherapy, about $100US and similar to a wrist watch. Positioning this according to the instructions is critical--if it slips off, it does't work. I find it outstanding, almost as good as Scopolamine but not quite.
And there's ginger, plain ginger powder as a spice, taken in capsules. It dilates the capillaries and increases blood oxygenation--so it may give you the hiccups but it works well enough that even NASA respects it.
And with any of them, getting that rest & prep beforehand, and USING the remedy an hour or more before you leave the land, is probably the most important part. Tell your mate to ply you with ginger tea next time.<G>
