I went to the docs before I went to NZ to get married and he prescrided me a nice big box of 5mg Diazepam .......
I did have a history of anxiety disorder so that maybe swung clinching the drug deal in my favour, but I reckon if you are up front about being scared of flying they will give you a small box
Other than that, there are a few Herbal remedies (Kava kava, Valerium etc)....but none give you the dunt you need
