I'm not sure I follow what you're saying. Why would halting lcohol consumption be a recipe for disaster when out at a restaurant or bar? The only thing that can reduce BAC is the passage of time. Let me know if I missed a secondary meaning to your post.

That's right, but an hour per drink is not enough. All coffee can do is make one a speeded-up drunk in the eyes of the law.
Any admission, or any alcohol consumption prior to driving; or for that matter, driving a new car, living in a new or recently-refurbished house, or recently being around paints, solvents, sealants, adhesives, fuels, lubricants, etc. can make you a candidate.
So can the Adkins diet, diabetes, smoking, ad nauseum.
In short, anyone driving who attracts the attention of law enforcement can be convicted of DUI.
I wasn't scolding you, I just want people to know what it's like out there.
