Stuff the pills, why are you so nervous?
It's worrying that you want to turn to medication when nerves is a totally natural phenomenon. Unless you have a medical condition (in which case you would likely already be on medication) why do you need pills?
Why don't you be a man, get a grip and get control of your nerves? People are busing having their limbs blown off in Afghanistan and there is you worrying about a driving test, you need some perspective my man.
Harsh words maybe, but overcoming fears on your own is part of growing up and will do you good. Face your fears...don't look for the easy way out.

Come on man your awesome enough to do this on your own!
