Good job dude. First few times I did it were so nerve racking it was unreal, get past that you can get past anything!

If you're gonna have a drink, I recommend coke for the sugar (it keeps me from getting hungry, but not red bull as it makes me too tense). Or let one of the group get a shot for you

Also, bonus is you can drive into town if you don't live there!

As for smoking, I go to the smoking area for a change of scenery and because its sometimes a bit noisy inside and I wanna talk and open with "Hi".
