Since you are asking and seem to be wanting to discuss, I will also add this. What you reveal here may have a lot to do with how the judge is feeling and ruling around these circumstances. First of all, great kudos to you for actually calling someone on your daughter to stop her from drinking and driving. I can to some extent understand how hard this must have been for you. And I understand the utter impossibility of making another person, no matter how much you love them, do what you want them to do all the time.
However, and the judge may feel this way too, when you describe your daughter's drinking pattern here, this turns out to be a much more serious reason to refuse her a lot of leniency or benefit of the doubt. Because party drinking, where you should have called an Uber, you and your buddies were out at a bar and you drove home buzzed....that's the kind of drinking that people tend to age out of. Where they've got to be young enough to have the desire to go out on the town and have friends that are also so inclined, where you're on the party scene. Well, you do get too old to really want to do that, and our lives and jobs and other interests take over.
But someone who has found that solitary drinking is a thing to use to "kill the pain" of something bad that has happened in their lives, that's something that you do not ever age out of wanting to do. Those kinds of drinkers keep doing it all their lives if they don't work really really hard to avoid it. I hope your daughter is still in her treatment programs, heavily involved in her steps programs, and that she can work out constructive ways to get where she needs to get without having special leniency given to her. I have known the personal misery of watching serial solitary drinkers stay sober and do well for four or five or even ten years, only to have them plummet back down later. You can never relax and think the problem is solved. My thoughts and prayers are with you and your daughter.
