how to prevent a hangover

Found this article via fitsugar:

• Don't drink, or at least drink less. Instead of having four drinks, try for two, maybe even one. Drink slowly, and as a rule don't consume more than one drink per hour to give your body enough time to break down the alcohol. Also, one drink does not mean a Long Island Tea. We're talking a beer, a small glass of wine, or roughly one ounce of hard liquor. Keep in mind that certain factors help determine your body's ability to metabolize alcohol: weight, height, and overall health. First of all, I clicked on this article to find out how not to feel shitty after drinking and your first tip is 'don't drink'? Are you fucking kidding me? Instead of having four drinks, try for two?!?!?! How many drinks does the bottle and a half of wine i drank last night count towards? And who the fuck drinks Long Island Ice Tea anyways? Sure it's like 6 different shots in a glass, but it's definitely a Ijustturned18 drink. Talk about a party pooper- drink slowly totally negates getting drunk, which is the point of drinking. This would also mean only doing two shots at the bar instead of 5 on top of the 5 beers to get you to do the shots. This person obviously doesn't realize that a hangover just means you had a fabulous time the night before.
  

• Drink water, and lots of it. Since alcohol dehydrates the body, begin and end your night of drinking with plenty of water, and for every alcoholic beverage you consume, match it with a glass of water.Try remembering this when you're shitfaced.
  
• Don't drink on an empty stomach. Having food in your stomach helps dilute the concentration of alcohol in your belly.This is why there are $2 pizza joints all over town. Amateur mistake.
  
• Be choosy with what you drink. Stay away from sugary and carbonated drinks because they speed up the absorption of alcohol into your bloodstream. Drink clear liquors over colored ones: darker alcohol like bourbon or red wine contain more of the toxic substance congeners, which help contribute to hangovers. Don't drink booze from the well either; the cheap stuff has way more congeners than the good stuff. So basically drink Grey Goose straight? Got it.
  
• Vomit and rally. If you clear the decks for more booze, you have the innate ability of building the amount of alcohol in your bloodstream while simultaneously extricating the booze that got you there. It's like getting drunk when you're already hungover. Easy and it feels damn good.
  
• Have crazy animal sex. It's like going for a run when you're drunk. You won't be super drunk at the end and you'll sleep like a baby.
• Keep drinking. Since a hangover is basically feeling shitty because of a dip in your blood alcohol level, if you keep drinking, you can completely avoid the whole thing. I recommend beermosas or ceasars for an acceptable morning beverage.
