What's the limit of alcohol to b charge with D.U.I.?

Depending on what state you reside, "over the limit" is usally 0.08 or higher on a breathalyzer. In most cases, that occurs after having between 1 and a half to 2 drinks withing an hour of taking a breathalyzer. Proclaiming to the police that you only had "two drinks" does not constitute sobriety during a stop. Because a breathalyzer analyzer detects only the alcohol detected in deep lung air, which is associated with pure BAC (Blood Alcohol Level) it is imperative that after the second drink that you supposedly had, you must wait at least 30 minutes for the alcohol to absorb, or metabolize through your system before you drive.
