I am prone to getting sea sick (even when I am scuba diving it happens) and have tried all of the natural and prescribed drugs to find a solution.
Well the only thing that works is the Transdermscop patches that go behind the ear. They are amazing. Only problem is - we can not buy them here in Australia at all. 
So if there is anyone out there who has any spare, is bringing some onto out cruise or can bring some, I would be happy to pay you for them.
