I've spent about 48 years on the water
. It became my profession (Navy) and always my hobby (sailing). I'm not going to say, don't use medication. But I will offer an observation. The only guaranteed 'cure' is to sit under a tree.
I know of only two people in my circles with 'time at sea' who have NEVER felt seasick. Lord Nelson
was a chronic sufferer as are many other noted mariners. It's so much a part of our world its often mentioned only in passing.
In the five years I sailed a square rigger in which every two weeks we would see a group of 24 kids
aged 16-23 (12 male, 12 female so a pretty useful sample group totaling around 500 a year) embark for a 10 day voyage, every one of them got seasick to some degree (from mild nausea to violent vomiting and dry retching). Only two required an anti-emetic injection and only one was landed unable to continue. I also noticed that those who took nothing might have been rendered useless but recovered within a day, those who used Scop or oral meds took two to three days. But all recovered. It was a fairly common occurrence for both ship's crew and trainees to be aloft furling sails
, vomiting and carrying on. In Navy
ships, some sailors walk around on the first few days at sea with a garbage bag in their back pocket ' for Justin (Case)'. There is an attitude that seems to build a faster recovery.
I would say I get mildly nauseated for the first few hours on voyages departing into poor weather
and my particular trigger is the oily swell and slow roll in little wind
. Rough weather
is fine. I've took meds occasionally in the early days but don't anymore nor for most of my career since. I expect it may happen and I work through it if it does.
My point is that there is an amount of time in which we adjust to the motion (brain, inner ear etc) and the same conditions which might make us sick early aren't so later. When we do irregular short trips we don't get to adjust and we also lose any 'conditioning' like fitness in which we remember the sensation and getting over it.
You can of course only know this would work for you by 'risking' it, but frankly its unlikely you will be completely disabled, you'll just feel like **** and throw up a bit, so it's worth a try rather than assuming a life needing meds to enjoy a life on the water
. If you are the only person capable of managing the boat
to a safe anchorage to recover, there is of course an argument about your crew learning
a little more which only reduces the pressure on you.
