I have never been on any kind of medication like that before but have felt increasingly anxious/panicky in general over last few months. I have a 4 hour flight in a few weeks and I am terrified of the claustrophobia and feeling out of control. I am not good on planes anyway but know I will be even worse this time. Someone suggested diazepam for the flight. If I go to the doctors and explain, do they normally sympathise and prescribe with this kind of thing? I don't want to be told to just basically get a grip!!
