Did they do the other wristbands, the one that use pressure points?
I swear by them!
I'd been on two cruises without them, back in the early 90s, and got very seasick the first night out. Both times I took medication that knocked me out.
In more recent days I've used the wristbands and I've not had a single moment of seasickness!
Believe me, I was skeptical and had some meds handy as a backup.
I thought the whole premise was silly ... but they worked!
My daughter's fiance was with us on a cruise last year and he got seasick the first night out. I gave him a set of wristbands and he was fine.
I take mine off the second day of the cruise -- he did the same. And he got sick! He put them back on and was fine.
