anxiety
"I have severe flight anxiety and was prescribed Ativan 5-10 years ago to take before flights.  It works really well, and gives me this deep feeling of calm that helps me not panic on planes.  I used to shake for an entire eight hour flight, and while my anxiety doesn't entirely disappear with a 2mg dose, it's vastly more manageable. 



I haven't really noticed any side effects aside from feeling sleepy and having my mind wander a bit."
