Ditto on getting here on time to respond, I used to work for a whale watching tour company - and I get insanely motion sick.
Sea bands, ginger, crackers, staying in the back of the boat, staying outside in the fresh air, and eating very thick oatmeal an hour before going on board (a Navy guy with 20 years of experience on 20 foot seas told me that one) with a dose of Bonine or Dramamine, and some coffee.
Those are my tips
"..I think you need to stop following misery's lead.
Shine away. Shine away. Shine away.
Isn't it time you got over how fragile you are?
We're all waiting on your supernova, 'cause that's who you are.
And you've only begun to shine.."
