I don't know but I went deep sea fishing in Cancun last month and got sea sick pretty good. My 1st time to go deep sea fishing. I took Dramamine in the morning but should have done it that night but we went out drinking. Our fishing trip didn't start until 11am...
I felt like crap. Puked 5 different times that trip. And the Dramamine made me super tired too. It was fun. ;-)
