I think you need to talk to a lawyer, before you go to court on this.  I'm not a Louisiana lawyer and I don't know the limit in your state, but most places it's no higher than .08, and you blew more than twice that.  The question here might be not whether you are going to jail, but for how long, and that's where an attorney can make a real difference for you.  One place to find defense counsel is our website, http://attorneypages.comYou should get credit for the day in jail, although the law and procedure on that can be different from one state to another.
