I certainly hope not. Don’t. Drive. Drunk.
If you do, then you should expect pay the full penalty. It’s as simple as that.
On the other hand…
As long as possible before you go to court, begin to actually change your life to prevent a repeat offense. Go to AA, seek counseling, consult your clergy person… Make an explicit, concerted effort to reform yourself so that you will not be in a position to drive drunk again, and keep careful records of your progress.
When you go to court, dress professionally, bring the records of your progress, and be completely respectful to the judge. When you are asked to plead, Plead “Guilty with an explanation, your honor?” Say it in the tone of voice of a question, to let the judge know that you are asking permission. If—and only if—s/he gives you permission to do so, then:
— Do be prepared, brief, professional and courteous.
— Do not make excuses: there is no excuse for drunk driving, period.
— Do be remorseful: make it clear that you know that driving under the influence was a stupid mistake that you do not intend to repeat.
— Do not burden the court with your troubles or blame your DUI on anyone else.
— Do let the judge know what steps you have already taken to prevent a repeat offense.
— Do not assume that any of the foregoing will keep the judge from throwing the book at you.
— Do shut up immediately when the judge asks you to. In fact, listen extremely carefully to all of the judge’s instructions and follow them completely.
— Do not interrupt or argue with the judge.
— Do mention that you have documented your progress, indicating your records.
— Do not attempt to read from your records unless asked to do so by the judge.
Whatever you may want to think, you deserve no leniency from the court. You did something selfish and stupid that could have killed or maimed you and others. But the judge is a human being who has the privilege to show discretion — but no obligation — to show leniency. The judge will have heard every excuse, dodge, sob story and line of BS that you can imagine.
You don’t have a leg to stand on. So, with dignity but not a hint of self-righteousness or self-pity, show the judge that you are reforming your life so that this sort of thing will never happen again. The judge may or may not care that you have documented your progress. S/he may or may not want to see your documentation. You almost certainly will not be permitted to read from them at length. Simply the fact that you took the effort to document your progress and bring it to court is what may matter.
