I take Diazepam or Xanax before a flight. Had a horrific experiance in America in 1998 when the plane literally just fell out of the sky. I was going from LA to Vegas on an internal flight. They use 737's, like our EasyJet's. All the oxgen masks came down, people screaming, being sick, etc. Since then I do 15mg of diazepam 1 hour before a flight. The Dr's doont like prescibing diazepam so 2 years ago when i was in Thailand I bought 200 10mg tabs as they are legal to buy there..... result!! I also bought 50 Xanax tabs as they are legal there too....... the ultimate tablet if you want to chill! I took a Xanax 1 hour before the flight the other month when I was fighting in Thailand, it was ace!
