We all know the classic hangover cures: a greasy breakfast, maybe an Alka-Seltzer.
Perhaps the most popular is the classic 'hair of the dog', powering through the pain with an order of bottomless mimosas.
But a new study has confirmed everyone's fears: that is actually the worst way to treat your headache, nausea, and general sense of doom.
As good as it feels, researchers say alcohol will only temporarily make you feel better by dulling your senses.
Eventually, your symptoms will come out - possibly even worse.
Drinking a 'hair of the dog' to cure a hangover is the worst treatment for it, a new study says
The idea dates back to the 16th century when a cure for a dog bite would be to bleed the wound out and place some pieces of hair from the offending dog directly onto the bite.
And though it didn't work, it gave rise to the notion that 'the hair of the dog that bit you' can fix your dog bite.
In other words, what cures you is what made you sick in the first place.
Or rather, another dose of the alcohol that put you in this dire situation can get you out of the resulting hangover.
Today, we attend boozy brunches with bottomless mimosas and Bloody Marys after a night of drinking. But they are far from an established remedy.
'There's no scientific evidence that having an alcoholic drink will cure a hangover,' said Dr Laura Veach, director of screening and counseling intervention services and training in the Department of Surgery at Wake Forest Baptist Medical Center in North Carolina.
'It will, at best, postpone one.'
Hangovers occur following the consumption of ethanol as found in alcoholic drinks.
The causes of a hangover are still poorly understood, but research suggests that there are several factors involved including dehydration and changes in the immune system and glucose metabolism.
The symptoms, usually some combination of headache, thirst, fatigue, dizziness, nausea and general grumpiness, reach their peak when the blood-alcohol level hits zero.
When you drink alcohol, it gets broken down in the liver to a compound called acetaldehyde, which is a toxic compound that contributes to the feelings associated with a hangover.
The more you drink the greater the buildup of toxin and, hence, worse
