For someone who gets seasick real easy the over the counter drugs don't work to good I've even been sick with the patch. The medicine that works the best for me is promethazine you need a prescription for it and a couple of sudafeds to keep you from falling asleep. Also no coffee or a greasy breakfast, if I think it's gonig to be rough I only drink water and eat crackers till I get a feel for what the water is going to be like. I have been out in pretty stinky conditions but I just get a little queasy if I take that stuff.
