Answer
It really depends on the kind of travel. if its a ferry then even before it sets off ,find a long seat and lie down . this really does work as i was told this by regular ferry travellers after i was sick for 5 hours on my first trip .now ,it never happens and ive told lots of people and its worked for them . planes are another matter and i still take good old quells when flying and up to now never been sick since . i used to be until i took them .
good luck
