Ed: The NASA research involves several heavy-duty drugs, one of which
is on the restricted list. That is why I am reluctant to post the
information on a public forum. I don't even know whether their use
would be legal under FAA requlations.

One of the drugs, Scopolomine, is readily available in the form of
anti-motion sickness ear tabs, and I am sure there would be no problem
using that alone. The other drug is not readily available, and I am
reluctant to name it.

For anyone who is still curious, I have written an account of my wife's
experiences (severe sea sickness completely cured), and I will be happy
to pass that along in private email: matt(at)takestockphotos.dot.com
Regards,

Matt
