I recently went to the doctors about my crippling fear of flying, she prescribed Diazepam 2mg to take 15 minutes before i get on the plane.

I have some questions about it, since i'm fairly new to anti-anxiety tablets.

Firstly what affects will it have on me? such as how will it relax me?

Also how long will it last? my flight is almost 5 hours long.

Thanks for the help,

Danni.
