There are few things as unpleasant as sea sickness. What you might not be expecting, however, is to feel the sensation of being sick and in motion once you're back on land; even though you felt fine on the boat. This phenomenon is known as "land sickness" or "mal de terre," and it affects many people who've been on a cruise ship, boat, or yacht at sea.
