I always use Dramamine, but I never really needed it on the cruise. I kept myself occupied, and it wasn't bad at all. But let me tell you, NEVER take a boat in Cozumel- that almost killed me. I was 11 and my brother was 10, he was throwing up everywhere
They have us some alchohol swabs and told us to sniff them. I was questioning that because it would kill brain cells. Luckily, I was fine with a bit of dramamine and some Mexican cola, on the ride back.
