Did you guys see the episode on MythBusters about motion sickness??
One of those two dorks (Adam highly susceptable to motion sickness) got on a some kind of mechanical bull to test out different remedies...funny as hell... as a control they had him on the mech-bull w/o anything and it took only a couple of minutes and he was blowing chunks.
They then proceeded through all the common over the counter stuff and I think the best he could do was around 20-25 minutes... that is, until they gave him ginger capsules, over two hours and he could have kept going longer.
Here's the episode summary:
Seasickness: Kill or Cure
The MythBusters tested various seasickness cures. They wanted to see if any non-pharmaceutical, no-side-effect remedy would work.
Motion sickness is caused by your brain being unable to process conflicting signals from your sense: your eyes tell you that your surroundings are still, but your inner ear and your fine muscle controls are telling you that things are moving.
Test setup
They built a chair modelled after NASA's seasick chair. The chair spun around at 7 rpm while the person in the chair was ordered to move their head to touch tennis balls positioned in front, behind, and to the sides.
Finding the test subject
They had to figure out who in the MythBusters crew was susceptible to seasickness. Adam was a sure bet because of previous seasickness during the Jaws Special. Sure enough, Adam got quesy within 3 and half minutes on the chair. After a half an hour in the chair, Jamie was still fine. Kari and Tory were both fine as well. Grant became the final test subject. He lasted longer than Adam, but he got sick as well.
Remedy Testing
Homoepathic tongue tingler. They used a unnamed spray that you squirt under the tongue as often as needed. Grant was sick within 10 minutes and vomited some small chunks. Adam was sick within 4 minutes.
Wrist straps:They wore little gray wristbands that are 'Barry Manilow's choice.' Adam was sick within 90 seconds. Grant got sick as well. They've gotten pretty quick with bringing a bucket to Grant.
*Ginger pills: It worked! Adam and Grant were both fine.
Small shocks on the P6 Accupunture point (on the wrist): Both Adam and Grant got sick.
Placebo: They told Grant and Adam they were getting an over-the-counter pharmaceutical remedy, but they actually gave them vitamins. Adam's reponse: "I hate this [bleeping] chair" after three and a half minutes. Grant: "This is among the most effective, if not the most effective."
Over-the-counter pharmaceutical drug: Worked on Adam and Grant, but it made them both a little loopy.
Only thing that worked without any side effects was the ginger pill.
