A couple of passengers signing up for trips this year have asked me about seasickness remedies. I am not exactly the best person to ask, as I am not particularly susceptible to this malady. I confess I might feel a little "off" for a short while at the beginning of a trip, especially if I did not get a lot of sleep the night before, but at most I might take a swig of Pepto-Bismol if I think the ocean will be rough.
Fortunately, I found an article on-line on the Bloody Decks website (a fishing website) that discusses seasickness medications. The author does not mention the availability of Scopolamine, which may not be available any longer. Note that ginger may be effective as a preventive treatment.
