I don't take anything going to Europe; it's too short. Going to Asia or Oz; I'll do 1/2 Xanax and whatever I'm drinking (which is usually champagne and a glass of port; if it's good port, I'll have a second glass ) and that's enough to get me to sleep. I don't do ambien except upon arrival to get to sleep first night and first night home and I haven't even been doing that lately. BTW, my dr. knows I do this. I recommend trying anything at home first - trying it on the airplane first can lead to bad, bad things
