If you want to try the "exotic" here are some "solutions" folks have pursued: 1. eat seafood before you depart; 2. drink alcohol; 3. stare off into the far horizon before you barf; 4. get behind the helm
and have something to occupy your attention; 5. avoid going down below; 6. avoid smelling diesel
fumes; 7. do not drink lots of water(normally before you barf, you get a very dry mouth); and 8. do not lie down.
For us we get sick regardless what we use and just put up with it till sea legs are in tack or the storm has passed. Its the dry heaves that really hurt. That vile yellow bile that offers no relief. In theory the old you get the less you get sea sick; but we are in our 70s and have not noticed that to be true for us. Happy barfing.
