I've been told "you either get over it or you die"....I guess I'm dying a slow death.
I have had the grey bands...didn't help me, but helped a lady that was on the boat.
I have the motion band, that gives you a little electric jolt every few seconds (like touching a cow fence)....doesn't go away for me, but makes it easier....I've passed it out to sickies on the boat and really saved their day.
For me, taking the pills with breakfast works good. On some days I sleep on the drive in because the pills just knock me out and am all good when I get there. I have tried them all, OTCR that is, and the generic ones do it for me, just as good as the name brands....even the ones you can get at K-mart.
Otherwise what the others have said, stay away from fumes, confined smelly places (the head), stay more to the middle of the boat if it should become rough....etc.
