According to a survey by the makers of Alka-Seltzer, 75% of adults drink regularly and are not put off by a fortnightly hangover.
Christmas parties and overindulgence are likely to bring more frequent after-effects as people around the country wake up to regrets about the night before.
Hangovers are a mild version of the withdrawal symptoms suffered by alcoholics.
Alcohol relaxes the blood vessels allowing more blood to circulate around the body.
This makes people who drink feel warm, but, if they drink too much the blood vessels can open too wide, causing nerve activity and pain.
Dehydration
Alcohol also causes an increase in urination which can lead to dehydration.
And the toxins or congeners in alcohol can irritate the stomach, causing vomiting.
It may also cause a build-up of acids in the blood, leading to a feeling of fatigue and general unwellness.
Some types of alcohol are more likely to cause hangovers than others because they contain more congeners due to the way they are fermented.
For example, darker drinks such as red wine, brandy and port tend to have more congeners than white wine, gin and vodka.
Champagne is particularly risky as the bubbles speed up the absorption of alcohol into the bloodstream.
Hangover tips
Alka-Seltzer has seven tips for Christmas drinking:
Cures
Ever since alcohol was invented, people have been coming up with new ideas for curing hangovers.
Most current cures are linked to a vitamin C boost or a big fry-up. They include cocktails of tomato juice and other foods high in vitamins and minerals.

In Puerto Rico people rub lemon juice into their armpits in an effort to see off the hangover blues.
In China, one cure involves drinking fresh tangerine juice and eating strawberries.
This seems more appetising than the ancient Chinese cure - eating a small amount of horse brain the morning after a night of overindulgence.
The Ancient Egyptians swore by a drink made of cabbage water.
In the Middle Ages, people ate bitter almonds and raw eel to scare off hangovers while in the 19th century chimney sweeps drank warm milk with a teaspoon of soot.
