If you're familiar with the experience of a bad night out, you might have a cure for it.
New research shows that most of the cures don't have any solid science behind them.
The scientific evidence for the effectiveness of any so-called "hobby cure" was not very good, according to a review of 21 placebo controlled trials.
The way in which these experiments are run needs to be improved, with a standardized scale used to weigh up the effects of various symptoms, rather than relying on self-reporting.
"Our study found that the evidence on these remedies is very low quality and there is a need to provide more rigorous assessment," says epidemiologist Emmert Roberts from King's College London in the UK.
The best way to prevent the symptoms of a bad night is to not drink alcohol or drink in moderation.
You may have tried clove extract, red ginseng, Korean pear juice, or both at one time or another.
The methods used to collect and assess data weren't of a robust enough standard.
None of the remedies were tested more than one time, and the results have not been independently replicated. Sampling was a problem, with eight studies involving exclusively male participants.
The amount of alcohol consumed, as well as the amount of food eaten before, were different in previous studies. The improvements in these areas might show which cures are effective.

The evidence isn't strong enough and further studies are needed to confirm the effectiveness of clove extract, tolfenamic acid, and vitamins B6 and pyritinol.
It's not surprising that there's a lot of interest in the potential of remedies to reverse the effects of alcohol, given our penchant for booze.
It's important to remember that binge drinking can have a negative effect on our cognitive processes, even if we have a good time the next morning. It's best that the hangover remains a warning.
People's employment and academic performance can be affected by depression.
The question of the effectiveness of substances that claim to treat or prevent a hangover appears to be one with considerable public interest, given the continuing speculation in the media.
The research has been published.
