my 2 cents:
Read a study that said the bands worked simply by placebo-effect.
Meclizine is somewhat effective. Also ginger has been shown to work.
I would never use scopalamine. Way too many side effects. Used to be used as anesthesia pre-op. Many kids had severe troubles. I have heard that Hal offers green apples to eat. Never heard of this before. Luckily I hardly ever get sick, but that ferry ride from Cozumel to Playa del Carma had a lot of people retching!
