No, I Haven't Heard About That....
but I did work for an Ensign in the U.S. Navy (for a short-short) who spewed chunks even as we slowly cruised out of San Diego habor passed the submarine base. Absolutely flat water. He was a bit the nerveous type. Saltine crackers are ALWAYS the best medicine. Don't leave port without them. Also, go see the man about buying a horse before you head out! LOL! All will be OKAY. CF?
