Transderm Scop (the patch) works well for me. A couple of pieces of toast for breakfast only and take saltine crackers aboard to munch on to neutralize stomach acid and keep a little something on your stomach. Keep your eyes on the horizon when possible and stay outside in the fresh air (avoid diesel exhaust at all cost). Do not go in the galley!!! Don't give a puker eye contact. Breathe through your mouth if the guy next to you creates a "cleanup on isle 5" situation on the deck. Don't start feeling too smug when you're the only one yet to blow. Good luck.
