Try this, it worked for me.....go to Walgreen's or any pharmacy and ask for their "Sea-Bands". Its a hard plastic nodule that is on an elastic band. Its placed over your wrist with the nodule pressing on the underside of your wrist on your medial nerve area. I was in 15 ft seas last May on the Carribean Princess and they worked like a charm!! Took 'em off just once, and in 5 mins began to get queasy!
