Looking at what you're facing with that Super Drunk Law, it's not worse than what we face here in Texas with just a regular ol' DWI, except for the whole interlock device that you have to have on your vehicle. Of course it's going to be on your record forever, but you can explain it to an employer if you are sincere about lesson learned and the fact that you have changed. I work in the education field. I got a DWI 1 year before the date I was hired. I may have gotten lucky, but I did get a job. I would think unless you're wanting to go into law enforcement, you can say it was the best thing that could have happened to you and some people will be willing to take a chance, as long as you mean it. It's not the end of the world.
You are who you are when you're not drinking alcohol. The quicker you accept it, the better off you'll be. I thought I was a better person while drinking at one point because I lost my mental filter. I would make an ass of myself more times than not.
