Hi Winter,
I have unfortunately been through 2 DUI's, (15 years ago) however there weren't any accidents involved. My BAC was over the top on both...2.35 and I was far from being falling down drunk. My tolerance was extremely high...
I can tell you that the other suggestions to get into a program are right on, the judge will consider what actions you are taking NOW. The courts care very little about our words, best intentions, and apologies.
I would find an approved "court ordered" facility to begin taking alcohol treatment classes, they can also test your BAC daily to document sobriety. Your probably gonna get this as part of your sentence--starting NOW will look good.
You can get through this, it's going to take time, money, and alot of action on your part. Get an attorney and take action now! I wish you the best of luck, and hope you come here for support. Please learn from this so you can avoid a repeat.........like me
