As far as I know, the only known antidote for alcohol poisoning is to get the victim to the ER...FAST! It is better to be safe than sorry. I have heard too many stories of people at parties trying to sober someone up by throwing them into a shower, giving them coffee,letting them "sleep it off". These are all dangerous and foolish ways of handling such a serious problem. Caffeine only makes the intoxicated person a wide-awake drunk; a shower can cause a severe slip/fall posing more threats, and sleeping it off can prove to be a fatal slumber...going into a coma and never reviving. There is also the very possible chance of someone drowning in one's own vomit while lying down severely intoxicated. When in doubt, seek medical attention IMMEDIATELY!!!!!!
