Have you ever watched "MythBusters" on Discovery Channel? These two guys are hysterical at times puting "myths" to the test, they were movie stunt coordinators, anyway they did the motion sickness myths - 2 of them were very susciptable and were the "guinea pigs" they sat in a chair that spun around slowly, and they would tell when to shut it down, and often they would need a garbage bucket to get sick in!!
They tested the wrist bands, the little ones, and the major expensive ones - neither worked...
they tested the dramamines, etc... and it worked, but then they had one take a placebo, and it worked too -
What surprised them the most was the ginger tablets worked the best!! They both concluded that they would feel comfortable reccommending ginger tablets!!
I personally do swear by the ginger tablets (you can get it at health food stores) ginger snaps, and ginger ale also are effective!! I also this time had my doctor prescribe the patch and wore it - I have some other interesting things, so when bromine, and dramamine were no longer effective, the doctor discussed trying the patch, and I'm glad I did!!
