Drink to safe limits. How to get rid of a hangover headache? Duh…don’t drink so much. The more you drink, the greater your chance of having a hangover with intense symptoms. The safe limit is not more than two drinks a day for men and not more than one drink a day for women. Try not to get into "drinking rounds" to make sure you control how much you drink.
Drink keeping in mind your tolerance level. Tolerance to alcohol differs across individuals. Do not drink more than what you can tolerate, or stop immediately when you feel intoxication setting in.
Don’t drink on an empty stomach. Food in the stomach slows down the absorption of alcohol. It is a good idea to eat fats or carbohydrate-based foods like pasta or rice before you drink.
Drink slowly. The quicker you drink, the more likely you are to drink an excess amount of alcohol. Drinking rapidly also increases the chance of an overdose that can cause alcohol poisoning.
Sip water or some other non-alcoholic, non-fizzy beverage in between alcoholic drinks. Sipping something non-alcoholic between drinks keeps you hydrated and ensures that you do not drink more than the safe limit. However, stick to a non-fizzy or non-carbonated beverage that won’t speed up the absorption of alcohol by your system.
Avoid dark-colored drinks. The darker the color of the drink, the higher its congener content. Light-colored or clear drinks like gin, vodka, and white rum are low in congeners. However, remember that if you drink too much, both dark-colored liquors and clear drinks will bring on a hangover.
Drink water before you go to sleep. This will keep you hydrated and prevent many of the symptoms of a hangover from occurring. Also keep a glass of water nearby, so you can drink if you wake up at night.
