Take precautions before planning a cruise trip or traveling in the ocean. For example, check with your cruise line that there is medical staff on board as well as nausea medication. Also, consider how the weather will be during your cruise, as storms could increase the symptoms of nausea.
Book a cabin in the middle of the ship if you are going on a cruise. The middle of the ship will experience minor bumps from the ocean during the trip. Think of your cabin as a safe haven to go to once you begin to feel nauseous.
Use an over-the-counter drug at least two hours before boarding the ship and once you feel nauseous and dizzy. For example, you can take dimenhydrinate or meclizine, which will help to suppress the nerve signals that are sent to your brain.
Restrict your use of alcohol once on the ship. Ingesting excessive amounts of alcohol will only heighten any feeling of dizziness. Also, eat moderately. Try not to enter the deck of the ship until you've digested your meals.
Consider an alternative method if the sea sickness continues, such as taking a ginger tablet or working on breathing exercises. For some people, controlling breathing by taking long deep breaths can stop the affects of sea sickness. Another method is to use an acupressure bracelet, which controls nausea by applying pressure above the wrist.
