I have only ever been seasick once (only when I went below, during a Force 10+ in the Bay of Biscay), and I never want to repeat the experience. So I'll use a preventative until I am sure I have my sea legs.
Stugeron is the bees knees. Yes, the recommended dosage of two tablets, makes you sleepy. So I don't take two. I take HALF of one tablet, at least 30 minutes before getting on a boat (even on Cross Channel Ferries), and will take another HALF at 24 hour ish intervals.
Zero drowsiness problems as a result.
When coming back to the UK on a CCF, there was a party of French mid teens youngsters on board, and two of them were suffering horribly - especially one girl, but both were too miserable for words. So I got permission to go down to the vehicle deck
, and collect the Stugeron from the tank bag on my motorbike, and gave the two sufferers two each, with instructions to put them under their tongue and not swallow them (they would have thrown them up) but let them dissolve there. Within 10 minutes they were both much better, within a few more minutes they were right as rain. I left the almost full packet of Stugeron with the party, so they could each take a half tablet 30 minutes before getting on the ferry
for their return journey a couple of weeks later.
On another occasion, I accompanied a friend on his post purchase
guided sail down the tricky estuary where the boat was moored, along with the previous owner. I offered them both a half Stugeron before getting on board, but both declined and said that they don't get seasick. Their choice.
After exiting the estuary on a superb sunny and calm morning, we dropped anchor
several 100 yds off the beach, and I left new owner and previous owner going over all the ins and outs of the vessel, while I disappeared below and put breakfast on. With a tray laden with bacon sandwiches, toast and marmalade*, and steaming mugs of tea, on returning above decks, rather than them sunbathing happily as I imagined, after their chatter ended, I found both of them to be literally green (I had never seen anybody actually green with seasickness before). The long, slow swell at anchor
, had done them both in.
Luckily I hadn't left the Stugeron in the car as I had intended, the packet was still in my jacket. So I sat and watched what happened to them, after they put two Stugeron under their tongues to dissolve.
Within 10 minutes, they were perking up, and the green was dropping from their faces, to be replaced with a deathly white. Within another 10 minutes, their colour returned to their faces
Breakfast and tea now stone cold, muggins had to go below and make more, while they lifted anchor and set sail for a harbour a few miles down the coast, where we planned to visit the pub for lunch.
When we got there and dropped anchor, prior owner and new owner were stretched out on the cockpit cushions
, and rapidly fast asleep, so I had to go to the pub and drink and eat without them.
Don't let anybody get away with suggesting different, Stugeron work, and HALF a tablet 30+ minutes prior to going on board, works really well too.
The only links I have with Stugeron are as a user over several decades, and as I am determined to always have as good a time as possible while afloat, I have never had a second occasion of seasickness ever since I started using them.
Prevention is much, much better than cure.
*Did you know Marmalade was a seasickness remedy? The name comes from Mal de Mer (seasickness in French).
