Now you’ve done it, it’s official you have a hangover, now what? No matter what you do sleep and water or juice should be included. There are many folk cures that are supposed to help cure a hangover. Many of them will help you cope by replenishing the vitamins and liquid you lost over night, while some like avoiding caffeine are very important to a quicker recovery. There is no one size fits all cure, find what works for you.
Difficulty: Hard
Time Required: As long as it takes to feel better.
Here's How:

1. Sleep. Rest is your best friend at this point to give your body a recover. It is best to stay in bed so call in to work if you have to, tell them you have the stomach flu. You will sound so horrible on the phone they may believe you (unless they saw you at the bar, not a good idea then).
2. Replenish your body with fruit juice and water.
3. Avoid caffeine. A weak cup of coffee may be okay but a lot of caffeine will continue to dehydrate you, the opposite of what you want right now.
4. Drink orange juice for Vitamin C.
5. Drink a sports drink like Gatorade or Powerade.
6. Eat mineral rich food like pickles or canned fish.
7. In Poland, drinking pickle juice is a common remedy.
8. Drink a Bloody Mary. While the popular phrase “hair of the dog that bit you” may sound logical with a shot of whiskey left in the bottle next to your bed, it’s only temporary. Try a Bloody Mary instead, while your blood is dealing with the new alcohol it is ignoring the old and in the mean time tomato juice and celery are full of vitamins. If you drank the last of the vodka make a Virgin Mary. Another spicy morning after drink option is Hair of the Dog, in which gin and hot sauce are sure to bite your hangover back.
9. Take a shower switching between cold and hot water.
10. In Ireland it was said that the cure for a hangover is to bury the ailing person up to the neck in moist river sand.
