Stugeron (not sure of the spelling) is an excellent tablet cure.
Also i have found those wrist bands with a stud in actually seem to work. Not sure if its mental or physical cure but if it works for me it might just work foe you

Sea bands from Boots or any good chemist I find work very well, Stugeron ok, but knocks me and daughter flat, so not so good if actually expected to do anything. Sucking lemons, or ginger good but horrid, ginger bix ok but bad for ballast. Stones ginger wine excellent for settling stomach at end of journey. Hayfever remedys work well, and you can get non drowsy ones. Stay upstairs, and keep busy if poss eg radar, look out. Don't read, do puzzles or play game boy, keep fluids up! Water, or weak squash, not fizzies. Keep bucket and wet wipes/flannel handy. Put long line on bucket so you can chuck it over the side and drag it along to clean it out.
Just remembered another one. You know the pads you get in sachets that you clean wounds with well have a sniff on one of them...instant cure. Apprently it is used in the medical profession for people who suffer with giddiness.
I guess I should also say take your doctors advice before sniffing.

he doesn't say if he wants to cure the seasickness, or CAUSE it?
Best way to cause seasickness is slip the lines, then hand out sick bags. Make sure that the last one has got some potnoodle in it, and say "ooh - a donation from last week!" and slurp it down, then handover the used empty sickbag to them "-is that okay for you or shall i rinse out?"
..used to do similar with Knorr <sp?> soups, way before they invented Pot Noodles. Always guaranteed to get a good gagging reflex going amongst the uninitiated. Not me though, far too grown up!
