Doug, Ginger Capsules
from the vitamin store worked for us. I don't like Ginger snap cookies or anything similar with Ginger so we have been using the capsules for sometime now. In fact a few years ago a TV program called Myth Busters on the Discovery Ch did a test of most motion sickness drugs/herb remedies, etc. and the person being tested found that Ginger worked over all the other things he tried. Being an old Navy Medic (circa Korea), I used Ginger on a number of sailors/troops prone to 'Mal-de-Mar" and it worked on the better part of those subjects.
