<p>On our first cruise I got so sick that I wound up going to the onboard doctor. I received an injection and anti anti nausea pills. The doctor explained that one of the contributing factors in seasickness is a reduced amount of oxygen in the blood. Another cause is the inner ears’ lack of ability to adjust. Twenty minutes later I was fantastic. And yes, the doctor asked about general health, possible exposure to the flu etc. </p>
<p>Yes, I asked the doctor if it was a placebo. No. And every cruise thereafter I have made the trip down to sick bay.</p>
