As long as you've gotten a few hours of sleep, you'll be OK to drive the morning after you've been drinking.
Power naps, even in the middle of the night, are not sufficient. Alcohol is processed out of the body at your body's own fixed rate. Your reflexes and other physical abilities can be affected for as many as 10 hours after you've finished your last drink (and this could be longer if you had a tremendous amount to drink).
If I have too much to drink, I can drink a lot of coffee to sober up quickly. Right?
Ha. Tell us another one! Drinking a lot of coffee after drinking too much alcohol may, however, increase your discomfort through the need to use the bathroom while being transported to the jail on DUI charges. Only time will remove alcohol from the system. It takes the body approximately one hour to eliminate the alcohol in one drink. An old saying goes, "give a drunk a cup of coffee and all you have is a wide-awake drunk.
Splashing cold water on my face or taking a cold shower will help sober me up.
Splash away! And by all means, take a cold shower. It may make you cleaner, but it won't sober you up or make you a safe driver. The deputies at the jail, however, prefer clean drunks and recommend showering prior to doing anything that will lead to your arrest, such as driving after you've been drinking.
