I'm flying long haul for the first time this year and it'll be about 10 hours each way. I'm anxious about flying as i hate feeling trapped and out of control, I've started taking a low dose of diazepam when i fly which does take the edge off. Longest flight I've done is only 4 hours and i have no idea how I'll cope for 10? I'll be on an Airbus so it'll have TVs in the seats with films and so on but how else can I pass all that time and keep calm?
