Stugeron
There is a pill called "Stugeron" that is available OTC in Canada and the Caribbean. It is Federally Regulated in the US, therefore, a prescription is required. I understand it even works AFTER the onset of mal de mer. It comes recommended from some friends cruising in the Caribbean for the last few years and currently on their way to the Galapagos. Strange side effects, though. See the link.P.S. I am fine with any sea conditions, but the admiral like "Motion Ease" (availabel at Wal Mart, now) as the other poster mentioned.P.S. I have heard that various forms of ginger will help also. I have bought ginger "chewable" taffy at some boat shows, locally.
