My 18 yr old swears by them. She hates that they look sort of geeky but says it is better than the alternative.
Do they work? Well, as someone who gets car sick if you go in reverse too fast, I say no. Neither does dramamine or bonnine (sp?) for me. If you are really prone to motion sickness like me, they may not work. They didn't for me. The only thing that worked was the patch and man did it work.
I will never use anything else again.
If you just get a bit of the tummy thing, you might do ok. Many people swear by them and ginger pills.
I purchased some called Queasy Bands on Etsy. They are great for sickness and look like jewelry. Check them out
I saw those and wondered if they worked as well as the Sea Bands.
I also get really motion sick and was looking into trying the sea bands. Something I'm wondering is how tight/loose to make them?
