I've done a lot of tall-ship sailing (mostly schooners but, latterly, in square-rig, much of the time either working aloft or in the galley!) and I've never found any fail-safe cure. Some people seem OK if they take this-or-that pill, some swear by the bands, others have old mother's remedies they use. For me, nothing works. I just chuck over the rail and get back to work - occupying the mind does seem to make things a bit better. After a couple of days at sea it usually eases until we get a real blow, then up it comes again.

I've yet to be convinced that any of pills and potions that people take are effective per se - I reckon there's a pretty large dose of faith-healing involved. What absolutely does not work is ligging around in your bunk feeling sorry for yourself!

When I had surgery on my digestive tract last year, they gave me cyclizine to prevent nausea, maybe it would work for me.....??
