I completely agree. I once took Ambien on a flight from San Fran -> London, but I didn't sleep. I suffered from crazy short term amnesia by the time I got to the other end, walking towards the Hilton just outside the airport in that long tunnel... I kept forgetting where I was and why I was there and then I'd snap back to reality. To the alarm of a friend that was supposed to be picking me up, I simply checked into the Hilton. What happened on the flight was another story altogether. I think I was repeatedly telling the attendants that I'd taken Ambien, they ended up shifting me to first class. Looking back, it was fun for reasons I won't talk about here - but belongs strongly in the recreational category. Sitter required.
