How long approximately does it take for BAC to go from .25 down to 0?
I have a breathalyzer that's accurate but the levels are going down very slowly. It went from .31 to .25 in a very long time. The person is question needs to drive in about 2.5 hours. (I won't let them drive even if their levels are below the legal limit .08; it needs to be at 0)
