Sea sickness cures and remedies

Sea sickness is probably the number one worry for first time cruisers so I thought it was about time I gave a bit of advice about what it is and how best to avoid/overcome it.

Sea sickness is caused by a conflict between your senses. You have a very sensitive canal in your inner ear filled with fluid that acts a lot like a spirit level. This controls your sense of balance. So whilst you’re on a cruise ship, even though you might not be able to feel it, this inner ear canal well be aware of the slight movements of the ship. However because your eyes are telling your brain at the same time that your not moving the conflict caused leads to the sense of nausea you experience. This is also what causes motion sickness on land, in a car for instance.

So now you know what it is, what can you do about it?
