How to Prevent a Hangover Before, During, and After a Night of Drinking

One way to avoid a hangover completely is to avoid alcohol entirely—staying sober or at least California sober. But even if you pride yourself on drinking in moderation, the dreaded hangover doesn't often play favorites. A hangover is caused by, among other things, toxic congeners present in alcohol and alcohol's diuretic effect which results in dehydration. Sometimes, the easiest way to cure a hangover is actually to prevent one in the first place (but not by avoiding cocktails altogether, don't worry). Being prepared with a hangover prevention plan will help you counteract a night (or day) of drinking and avoid feeling sick tomorrow. Here are the best, proven hangover prevention tips from doctors and experts—forget hair of the dog—as well as potential remedies if those hangover symptoms still hit the morning after a big night out.

How to Prevent a Hangover Before You Drink

Eat fatty foods

All foods, especially fatty ones, delay the body's absorption of alcohol, doctors say. And delaying the absorption of alcohol is a good step toward avoiding a hangover. An easy food to eat before going out that's filled with healthy fats is avocado—so you won't regret an order of guacamole for the table.

Eat high-fiber foods

Chris Meletis, the dean of naturopathic medicine and chief medical officer at the National College of Naturopathic Medicine, explains that high-fiber foods—like Brussels sprouts, lentils, and popcorn—break down alcohol and absorb it, keeping it from reaching the bloodstream as quickly.

Load up on vitamin C

Often touted for its cold-fighting powers, vitamin C may also guard against hangover symptoms. Here are three delicious ways to sneak more vitamin C into your diet.

How to Prevent a Hangover While You Drink

Avoid congeners

Avoid what? Congeners are the compounds that give liquor its flavor and color. Every type of alcohol contains congeners, but dark alcohols, including red wine and whiskey, generally have more of them than lighter ones. These toxic chemicals may set off an inflammatory response that helps bring on hangover symptoms.

"Opt for lighter color, highly filtered alcohol," says Jeffrey Wiese, a professor of medicine at Tulane University. Typically, the more expensive the alcohol, the more filtered it is and the fewer congeners there are to cause a hangover. SKYY Vodka, for instance, makes a point of its "four-column distillation," "three-step filtration," and "exceptional purity."

Watch out for sulfites

Wine—especially red wine—can contain sulfites, which can cause headaches in people who are sensitive to them, even before hangover symptoms set in.

Stick to one kind of drink

You can keep better track of how much you're drinking, and you're less likely to upset your stomach.

Avoid carbonation

Research has found that the presence of bubbles—either in a carbonated beverage like champagne or in a still liquor mixed with sparkling or tonic water—can speed up the rate of alcohol absorption. The carbonation can cause the surface area of the stomach to expand, which leads to increased alcohol absorption (and higher likelihood of an unpleasant morning after).

Alternate with water

Drinking water during the festivities really is a good way to keep a hangover at bay. One, it replenishes your hydration levels, which is key to hangover prevention since alcohol is dehydrating. Water is even more important when you mix alcohol with caffeine, which doubles the dehydrating effect on your body. And two, alternating will help you pace yourself with the hard stuff.

How to Prevent a Hangover After You Drink

Sleep in

We all know sleep is restorative, and sleeping in (or going to bed early) can help your body recover and reset after an evening of drinking. Just keep in mind that drinking alcohol can impact your sleep quality and length—so this may be easier said than done.

Drink lots of water

Think of it as a cleansing rinse cycle. Alcohol consumption causes you to urinate more often, which leads to dehydration. After a night on the town, sip on even more water than you usually need to.

Grab some Pedialyte

Yes, this drink is often given to kids who need to hydrate, but Pedialyte has also made a name for itself as an effective hangover buster for the 21-and-older crowd. The hydrating formula, which you can buy in several different flavors and forms (powder mix, sports drink, ice pops), replenishes sugars and fluid-balancing electrolytes—essential during a hangover.

Eat bland carbohydrates

Hello, dry toast and oyster crackers. Plain carbs help absorb any alcohol left in the stomach, provide sugar, and combat nausea.

Add honey

A good way to combat low glucose is by spreading a tablespoon or two of antioxidant- and fructose-loaded honey onto your morning toast.

Eat eggs

Nutrient-rich eggs contain the amino acid cysteine, which can help clear the liver of harmful free radicals. Here are 11 easy egg recipes you can whip up next time a round of drinks leaves you feeling under the weather.

Take a non-steroidal anti-inflammatory, like ibuprofen

Non-steroidal anti-inflammatories provide headache relief without upsetting the stomach. (Be careful not to make a habit of relying on pain-relievers containing ibuprofen, since some doctors warn they react with alcohol to damage the liver.)

Exercise (if you're able to)

Listen to your body: If you're basically incapacitated from a hangover, forcing yourself to work out probably isn't wise—you're excused to lie on the couch and make people bring you things. However, if you're up for it, many people swear by a good sweat for clearing the hangover fog. Getting mild to moderate exercise increases circulation and metabolism and can rid the body of toxins.
