Holy shit... What a thread.
For real Southern... You got off very lucky. The cost of a DUI could easily exceed what that truck was worth, and that's not even going into if you'd hurt yourself or someone else.
The bad thing is that drinking and driving, as destructive as it is, is still pretty damned socially acceptable. I did it, and I got in a whole world of trouble with it too. I feel very lucky that a DUI was all I managed out of it, but that was enough for me. I don't drive if I've had so much as a sip. I've worked in bars most of my life and see it all the time. People don't call cabs, most people don't have DD's... it's just the way it is, and it's pretty damned scary how acceptable it is. Growing up it was the same way... Everyone I knew did it. Stupid as hell, but again, that's the way it was. No one is going to fist fight you over your keys. Off duty Cops come into my work, get loaded and drive home... How's that for a social deterrent?
Most people who get a DUI, or have an incident like yours, will swear off the booze for maybe a month or two. When the shock wears off they care a little less and maybe have a drink or two and drive, and justify it because they've "only had one or two...." Then before long they're back at it full force. Because "What's the odds of it happening again?" and "They're going to be more careful drinking and driving this time, because they've learned their lesson already." Obviously not.
I know people who've had 3, 4, 5, DUI's and are such fucking idiots... They still don't get it.
Awhile from now all of this will be behind you man, but don't forget how you feel right now, and what a dumbass thing it was that you did. Even leaving out the harm you could do to yourself or others... The cost of your truck or a DUI could buy you years and years worth of cab rides, unless you're a total lush, without all of the negative implications.
There's no one here who hasn't done something incredibly stupid, and most have probably drank and drove more than a few times... The real test of stupidity is if you continue to do the same stupid thing over and over and expect different results. Good luck to you.
