A couple of years ago I read though a fair part of the published research on ginger and seasickness and discovered that about half the studies showed a statistically significant effect and half didn't. So the jury is still,out on ginger, but don't forget the placebo effect - if you think that something may help you, it is quite likely that you will get some benefit. Of course, the same applies to drugs like Stugeron - I find it very effective but know a few people who would sooner have the seasickness. Keeping warm, avoiding tea and coffee and feeling confident in your shipmates are all likely to reduce chances of feeling bad.
I use ginger - but you do need quite a bit. Ginger biscuits have so little in them, doubt they would help.
Seriously, I took advice from much-experienced friend. Get crystallised ginger, put small bag in pocket. Nibble before setting off, and constantly have small bits throughout journey. Never been seasick since, and I used to get queasy on a car ferry on a calm day.
gingernuts and boots own brand of tablets. more efective and you can take them 20 mins before departure or if grey skys are ahead. also have some maltese ones which put you to sleep...
Stugeron works fine for me. I take one tablet on the second rough trip of the year (I usually forget on the first!) and its effect lasts all season! My packet of pills says use before 1985 but they still work fine.
Stugeron never worked for me......I swear by Boots own brand, Travelcalm. I carry some on board, and with me, and years ago anchored in Osbourne Bay for luch on a Day skipper course, the gentle popple made us all a touch queasy. Travelcalm all round saved the day..
scopalamine patches (hyoscine), on prescription , work if put on in advance, but dry mouth, sleepiness and 'High', detached feeling.
Boots own- Travelcalm- hyoscine- work, very quickly, not too bad dry mouth/tiredness
Ginger and mandarin tea- I've only tried it when I wasn't likely to be feeling sick anyway. Nice though.
Taking the helm/ keeping busy- better than nothing; BUT best of all is when I'm actually skipper- a purely psychological thing.
I used to get really sick (loss of all control of guts- both ends! and head) but the more sailing I've done the better I feel- again, psychological, the more confident/less scared I am the better.
