It does get easier...
living on an island makes you fly a lot to be honest.
sometimes i still freak out for no reason at all on a flight, and some flight are like im sitting in the bus. dont know why that is
and dormicum, on long flights i take dormicum, it makes you forget stuff, and makes you fall asleep.. winning!
I now only get nervous when landing in bad weather. But that took me about 100 flights, I think ;) I tried chill pills once and they made me feel even worse. Glad they work for you!!
