Maybe that's why you get sick.
I think it was the only thing that helped the last time.
It usually doesn't bother me at all unless it is conditions like this. The last time I was on a ship with anything "remotely" close to these type of conditions was on the Celebration coming back up the S.E. coast from JAX. It was right after a Hurricane/Storm had went through. Forget going to the cabin on that cruise, I had a porthole in the front of the ship. Just because the cruise line is named Carnival, I didn't think my cabin would turn into a Carnival ride.
I rode it out mid-ship on the Lido, with a Meclizine and a bucket O' beer. Maybe the seas subsided or something. All I know is I sure felt better after.
