theres some shit called Dramamine sold over the counter for motion sickness on boats, my friends used to take like 10 times the dosage and it would fuck them up beyond belief, like the couldnt stand up because they felt like they weighed 1000 lbs and they hallucinated and shit...i never tried it though
Dramine works and they have a less drowsy formula out. I've used the band around the wrist and that works to when i was in Cancun on the flight, snorkeling.
