All good advice. Booze does help. Look at this way, you're waaay safer at 34000 feet with all the traffic being controlled around you than say...on the QEW. I mean, there are hundreds of people on the ground (controllers, supervisors, etc..) whose sole job that day is to make sure you land safely. Anybody care about your welfare on the QEW?
Myself, I love flying (except for delays) and everything about it. The hum of the engines, the motion of the plane, the awesome view, etc. It's like being in the womb to me. I once slept from the tarmac in Philly to about 30 minutes out of SFO. Relax and try to enjoy.
