Motion sickness on other modes of transport doesn't seem to have any relationship to seasickness. My husband is hopeless travelling by road, unless he's driving, but has never been seasick. I'm fine by road but was very surprised to be sick when sailing from Kirkwall to Reykyavik (small ship, force 9!!!). Take a tablet such as Stugeron before sailing and if you fell unwell lie down until it stops. Remember most of your time at sea will be at night anyway. After a rough 24 hours I was convinced the ground was moving in Iceland - they have earthquakes there - but it wasn't, it was my ears compensating for the movement that had stopped! Have a lovely holiday and hope for calm seas.
No it does not necessarily follow but the chances are slightly increased that you will feel something. Some people can be very unwell in a small anchored row-boat, I am one of them, but I have never missed a breakfast on a cruise and I do not have to take anything.At any rate, nowadays there is no need for anyone to suffer sea sickness as they are plenty of proprietary brands around or at hand on board to counter this.
November in the Med can be a pleasant time of year but you can hit some pretty strong weather too then so be aware of this.
One last suggestion is that if things get rough, ask the captain if you can drive the ship for a while he's sure to say yes.
There's a very good chance that you won't be seasick. My wife was dreadfully ill on a small boat 'evening cruise round the bay' during our honeymoon in Jersey way back in 1965, and on various small boats and ferries since then. We therefore approached our first cruise (Airtours' Sundream in about 2000) with some trepidation, but were surprised to have no problems at all. We've since been on about ten other cruises, including the Destiny, still with no problems, even though we had several rough nights around the Med when a quite a few people were ill. We assume the stabilisers make a difference - they seem to damp out the worst of the movement, so you just get a fairly gentle swell rather than the fast rocking/twisting motion of a small boat.
Our advice would be not to stay in your cabin, with nothing to take your mind off it, but to go to one of the larger lounges where there's still something going on.
If you are affected, though, we've heard that the injections offered on board (around £30, I think) are very effective and quick-acting.
Enjoy your cruise, and don't spoil your pre-cruise excitement by worrying about something that almost certainly won't happen.
My husband also suffers from seasickness and the last injection given to him by the ship's doctor on board Swan Hellenic cost him £100 it was quick acting and made him sleep all day. The following day the seas were calm and he felt better. You could try ginger tablets these sometimes work.
