I get motion sickness (car, boat
, bumpy plane rides). It takes about 3 days for my 'sea legs' to kick in - and yes, once they have done, land sickness is a real thing. A small price
to pay for being on the water
Pills make me dopey and are not great when I need instant relief - apart from being on the helm
, I swear by this thing The Sea Sickness
Relief Band. https://www.amazon.co.uk/Reliefband-.../dp/B00PG4NUOS
Have used it for 12 years- it has only ever failed me once, during the Round the Island Race
in 2011 (Round the Isle of Wight) in the most appalling conditions. Even folk who took Stugeron (AKA Stagger-On) were moribund so I don't consider that a failure of the band necessarily.
