The best cure for hangover is to eat and go back to bed. Sadly, it’s a weekday and you do not have that luxury.
Some theories say that what causes hangover is that alcohol disrupts biological rhythms; others that alcohol withdrawal is the culprit of hangover.
Research say the headache may come from dehydration — alcohol is a diuretic — and your body’s adjustment to your dropping blood alcohol levels after you’ve stopped drinking.
The second way to avoid a hangover is very simple - Don’t drink.
Well, since that isn’t happening either you should try the following.
Eat Fatty Food before You Start
One longstanding folk remedy is to take a spoonful of olive oil before a party. Some swear by it. Eating a pizza or other fatty food has the same effect. Both are said to grease the intestines so the alcohol takes longer to absorb.
Consume sugar while you’re drinking. Studies show that fructose may speed alcohol metabolism, thus reducing the risk of a hangover. It’s important to eat sugar while you’re drinking, not before, since fructose metabolizes quickly. Try plain orange juice between cocktails.
Drink water.
It’s important to stay hydrated while you're drinking alcohol. That means drinking plenty of water between cocktails. If you bypass that rule and wake up groggy the next morning, drink up to rehydrate and flush the impurities from your system.
Drink Fluids.
Water isn’t enough. You need to drink electrolyte-rich fluids, too — like sports drinks, coconut water, or bouillon soup — that can restore the salt and potassium you’ve lost.
Eat breakfast.
Bananas, dates, eggs, whole wheat toast with honey, oatmeal
Electrolytes in food help replenish a dehydrated system and get calories back into your body. But go easy. While a greasy meal before drinking may help, a hangover needs foods that are easy to digest, like toast and cereal. Some believe that eating burnt toast will help, with the charred carbon crust filtering out impurities much like a carbon water filter. But there’s no research to back it up.
Eat ginger.
For centuries, people have taken ginger to reduce nausea and vomiting. Try nibbling crystallized ginger in the aftermath of a night of drinking. The National Institutes of Health reveal early research that consuming a combination of ginger, tangerine pith, and brown sugar before drinking decreases nausea and vomiting.
