It sounds like you were drunk. The fact that nobody was hurt doesn't change the fact that you'd had a few drinks too many. If you were not technically drunk (as defined by law) you were still drinking and driving, something that's not anything to put on a life resume. Having said that, I sure don't want my life resume published, but that doesn't change what you did.
I'm not angry or MADD either...but hey, you drank alcohol and then you operated a lethal weapon. What about that do you not understand? You could have killed someone and changed the lives of many people other than the unlucky and innocent person you killed.
Life is short. I suggest you consider accepting punishment for foolish, dangerous, negligent behavior...and go on. Taxi cabs are cheap considering the potential outcome of driving after drinking behavior.
