Simple... Be honest.. If you feel that you have to "beat" it, chances are you know already what to say and what not to say.
Key questions to be honest about include "Have you ever operated a vehicle or heavy machinery while under the influence of drugs or alcohol." The answer is "yes." If you haven't then you wouldn't be there. They know that, and they are looking for contradicting answers to flush out liars. They will automatically send these people to treatment.
If your BAC was above a 0.20 they will automatically treat you.
Show that you don't need alcohol, and they won't treat you.
If it's your second offense, be prepared to be treated.
