Thanks for posting this information on sea sickness. (NOTE to readers: a few days ago I asked which deck to choose on the Mariner... since the headline didn't mention "sea sickness" I thought I might post his response here under the correct heading, in case someone was looking for some help!) Thanks again Javert!
RESPONSE BELOW... re: "Sea Sickness"
There is a motion sickness oil and I believe it is called Motion Eze and is sold at Walmart right next to the dramamine. You dab it on behind your ear just like the patch and I swear it works. I've never been sea sick and I've given it to people onboard who felt a little queasy and they've all told me it helped. Only costs about $5.00. Worth having just in case!
I found the Scopalomine patches the doc prescribed very helpful for the vertigo feeling, but if its nausea, the ship I was on recommended eating green apples, and they were very available to the passengers.
