PSA for the newly or soon to be newly 21 crowd.
Never drink yourself to the edge of oblivion in public. Know yourself and your limits and don't discover them when you out having a grand old time. That is when horrible things happen to good people.
If you are out and start to see the cliff of oblivion coming up fast and your car ain't slowing down, at that time its too late to start developing an evacuation plan. Getting in your car to go home now would be the equivalent of throwing the car in reverse, doing a 180 and slamming on the accelerator.
A supremely dumb idea.
Drinking water and eating some starch would be a good way to toss an anchor out the door of the car. A really desperate maneuver is to drink a large glass of milk. Hopefully it will curdle and cause you to create a glorious technicolor yawn. Once you are done shouting at your shoes, you will have removed all of the alcohols backup forces and can work on just processing the ones who have already infiltrated your defenses.
Be smart in advance so you can still take measures after your brain has packed it's bag, put on his fedora and walked out in disgust.
