I get airsick. Or at least I did when I was a kid and I don't take any 
risks with that anymore so I get good and doped with dramamine or 
meclizine before I get on an airplane. Do these act in different ways on 
the body? How do they prevent nausea, vomiting and dizziness? Why is 
drowsiness a usual side effect? Do all antihistamines have the same effect 
on motion sickness? I have heard ginger (which acts on the stomach rather 
than the nervous system) is also effective... what's the most effective? 

Thanks!
