I never get seasick, but (how OCD is this?), when I board, I always run down to the desk to get the bonine tabs they hand out. I never end up taking them, and I now have a small stockpile of them. I guess it's better safe than sorry.

:)

p.s. I am so glad we have our resident traveling doctor, Masaki, with us! Thanks for all your professional advice Masaki!
