Which of the following is the most reliable method for someone who has consumed alcohol to regain sobriety?
The passage of time
Drinking several glasses of water
Drinking one cup of coffee per serving of alcohol you consume
Taking a brisk walk
While some of the other methods may be considered anecdotally useful, BUT in the eyes of the law (and the BAC counter), the only foolproof method of sobering up is simply to wait an appropriate amount of time.
