I have a dwi too and, like you, had a high BAC. I see a lot of comments saying you won't get jail time because it's a first offense, but you being twice over the legal limit will likely need to be addressed in court - you can't really argue that you only had 1- 2 drinks before getting behind the wheel.
In my state, being 2x or more over the limit is a gross misdemeanor DWI (vs just a regular misdemeanor) which means higher fines and longer probationary periods for getting back your license, etc.
Can you really be sure you won't ever do this again?
I agree with the others, go to some AA meetings, and listen and learn. You can get past this but don't sweep it under the rug. You are very lucky you didn't hurt yourself, your friend, or an innocent bystander!
