The age-old adage “beer before liquor, never been sicker; liquor before beer, you’re in the clear” has been passed down through generations of drinkers. This popular drinking rule suggests that the order in which you consume alcoholic beverages can significantly impact how you feel the next day. But is there any scientific truth to this widely believed saying, or is it just another drinking myth?
Understanding the facts about alcohol consumption and hangovers can help you make informed decisions about drinking and potentially reduce the unpleasant after-effects. Let’s dive into the science behind this common belief and explore what really matters when it comes to preventing hangovers.
Understanding the “Beer Before Liquor” Saying
This rhyming phrase has become deeply embedded in drinking culture, particularly in the United States. The saying implies that if you start your evening with beer and then switch to hard liquor, you’re more likely to experience severe hangover symptoms or even get sick during the night. Conversely, it suggests that beginning with liquor and transitioning to beer will leave you feeling better.
The popularity of this saying can be attributed to its catchy rhyme and the fact that many people have anecdotal experiences that seem to support it. However, personal experiences can be influenced by numerous factors beyond just the order of drinks consumed.
Where Did This Belief Come From?
Several theories attempt to explain the origins of this drinking rule:
The Progressive Drinking Pattern Theory
One explanation suggests that people typically start their evening with lower-alcohol beverages like beer or wine and gradually move to stronger drinks as the night progresses and inhibitions decrease. By the time someone switches to liquor, they may have already consumed a significant amount of alcohol. When they feel sick later, they attribute it to the drinking order rather than the total volume consumed.
The Blood Alcohol Spike Theory
Another hypothesis focuses on how different alcoholic beverages affect blood alcohol levels. Hard liquor contains significantly higher alcohol content than beer—typically 40% alcohol by volume compared to beer’s 4-6%. The theory suggests that switching to liquor after beer can cause a rapid spike in blood alcohol concentration, potentially intensifying hangover symptoms.
Proponents of this theory argue that starting with liquor allows your body to process the high-alcohol content early in the evening, and switching to beer later may slow down the rate at which your blood alcohol continues to rise.
What Does Science Actually Say?
Despite the widespread belief in this drinking rule, scientific evidence doesn’t support the idea that drinking order affects hangover severity. Here’s why:
Alcohol Absorption Works the Same Way Regardless of Order
When you consume any alcoholic beverage, your body begins absorbing the alcohol almost immediately once it reaches your stomach and small intestine. The alcohol from all drinks consumed throughout the evening will be completely absorbed long before hangover symptoms appear the next morning.
Your body doesn’t distinguish between alcohol from beer versus alcohol from liquor—it processes ethanol the same way regardless of its source. The total amount of pure alcohol consumed is what matters most, not the order or type of beverage.
Research Findings
A study examining drinking behaviors and hangovers found that the order of alcoholic beverage consumption had no significant impact on hangover severity. What did matter was the total volume of alcohol consumed and individual factors like body weight, genetics, and whether food was consumed with alcohol.
The misconception likely persists because people tend to remember patterns that seem to confirm their beliefs while overlooking instances that contradict them. This is known as confirmation bias.
What Really Causes Hangovers?
To understand why the drinking order myth doesn’t hold up, it’s helpful to know what actually causes hangovers:
Dehydration
Alcohol is a diuretic, meaning it increases urine production and can lead to dehydration. This dehydration contributes to common hangover symptoms like headaches, dizziness, and fatigue.
Acetaldehyde Buildup
When your liver metabolizes alcohol, it produces acetaldehyde, a toxic compound that can cause nausea, sweating, and rapid heartbeat. Your body needs time to break down this substance into less harmful compounds.
Inflammatory Response
Alcohol triggers an inflammatory response in your body, which can contribute to hangover symptoms like difficulty concentrating, memory problems, and decreased appetite.
Blood Sugar Fluctuations
Drinking can cause your blood sugar to drop, leading to fatigue, weakness, and mood disturbances the next day.
Sleep Disruption
While alcohol may help you fall asleep initially, it disrupts your sleep cycle and prevents you from getting quality rest, leaving you feeling tired and irritable.
Factors That Actually Affect Hangover Severity
Instead of worrying about drinking order, focus on these proven factors that influence how you’ll feel the next morning:
Total Alcohol Consumption
This is the single most important factor. The more alcohol you consume, regardless of type or order, the more severe your hangover is likely to be. Your body can only process alcohol at a certain rate—approximately one standard drink per hour for most people.
Drinking Speed
Consuming drinks rapidly leads to higher blood alcohol concentrations and increases hangover risk. Pacing yourself and alternating alcoholic drinks with water can help moderate your intake.
Food Consumption
Drinking on an empty stomach allows alcohol to be absorbed more quickly into your bloodstream, leading to higher blood alcohol levels and potentially worse hangovers. Eating before and while drinking slows alcohol absorption and provides your body with nutrients it needs to metabolize alcohol.
Hydration Status
Starting your evening well-hydrated and continuing to drink water throughout the night can help counteract alcohol’s dehydrating effects and reduce hangover severity.
Type of Alcohol and Congeners
While the order doesn’t matter, the type of alcohol might. Darker liquors like whiskey, brandy, and red wine contain higher levels of congeners—chemical compounds produced during fermentation that can worsen hangovers. Clear spirits like vodka and gin contain fewer congeners.
Individual Factors
Several personal characteristics influence hangover susceptibility:
- Body weight and composition: People with lower body weight typically have higher blood alcohol concentrations when consuming the same amount as heavier individuals
- Genetics: Your genetic makeup affects how efficiently your body metabolizes alcohol and acetaldehyde
- Sex: Women generally have lower levels of the enzyme that breaks down alcohol, leading to higher blood alcohol levels
- Age: Hangovers may become more severe with age as your body’s ability to process alcohol decreases
- Tolerance: Regular drinkers may experience different effects than occasional drinkers
Smoking and Other Substances
Using tobacco while drinking is associated with more severe hangovers. The combination can intensify dehydration and other negative effects.
Sleep Quality and Duration
Getting adequate rest after drinking helps your body recover more effectively. Poor sleep compounds hangover symptoms.
Effective Strategies to Reduce Hangover Risk
Instead of relying on drinking order myths, try these evidence-based approaches:
Set Limits Before You Start
Decide how many drinks you’ll have before you begin drinking and stick to that limit. Having a plan makes it easier to moderate your consumption.
Eat a Substantial Meal
Consume a balanced meal containing protein, healthy fats, and complex carbohydrates before drinking. Continue snacking throughout the evening if possible.
Alternate Drinks with Water
For every alcoholic beverage, drink a full glass of water. This helps you stay hydrated and naturally slows your alcohol consumption.
Choose Your Beverages Wisely
If you’re prone to hangovers, opt for drinks with fewer congeners. Clear spirits mixed with non-sugary mixers may be easier on your system than dark liquors or sugary cocktails.
Pace Yourself
Limit yourself to no more than one standard drink per hour to give your body time to metabolize the alcohol.
Avoid Mixing Alcohol with Medications
Many medications can interact dangerously with alcohol. Always consult with your healthcare provider about potential interactions before drinking.
Take Vitamins and Supplements
Some research suggests that certain vitamins and supplements may help reduce hangover severity, though results are mixed. B vitamins and vitamin C are commonly recommended.
Get Adequate Sleep
Allow yourself plenty of time to rest and recover after drinking. Your body needs sleep to repair and restore itself.
Other Common Drinking Myths Debunked
“Mixing Different Types of Alcohol Makes You Sicker”
Similar to the beer-before-liquor myth, the belief that mixing different types of alcohol worsens hangovers isn’t supported by science. What matters is the total amount consumed, not the variety.
“Coffee Will Sober You Up”
Caffeine may make you feel more alert, but it doesn’t reduce your blood alcohol concentration or speed up alcohol metabolism. Only time can do that.
“Taking Pain Relievers Before Bed Prevents Hangovers”
Taking pain medication before sleeping can be dangerous, particularly when combined with alcohol. Some pain relievers can cause liver damage when mixed with alcohol. If you need symptom relief, consult your doctor about safe options.
When to Seek Medical Attention
While most hangovers resolve on their own within 24 hours, severe symptoms may require medical attention. Seek help if you experience:
- Severe confusion or difficulty staying conscious
- Vomiting that won’t stop
- Seizures
- Slow or irregular breathing
- Blue-tinged skin or pale complexion
- Extremely low body temperature
- Loss of consciousness
These symptoms could indicate alcohol poisoning, which is a medical emergency requiring immediate treatment.
The Bigger Picture: Responsible Drinking
Rather than focusing on drinking order or trying to outsmart hangovers, the most effective approach is to drink responsibly and in moderation. The Dietary Guidelines for Americans define moderate drinking as up to one drink per day for women and up to two drinks per day for men.
Remember that no amount of planning or strategy can completely eliminate the risks associated with excessive alcohol consumption. Heavy drinking can lead to serious health problems including liver disease, heart problems, certain cancers, and alcohol use disorder.
If you find yourself frequently experiencing hangovers or feel unable to control your drinking, consider speaking with a healthcare provider. They can provide guidance and support for developing healthier habits.
Conclusion
The saying “beer before liquor, never been sicker; liquor before beer, you’re in the clear” may be catchy and memorable, but it doesn’t hold up to scientific scrutiny. The order in which you consume alcoholic beverages has little to no impact on whether you’ll experience a hangover or how severe it will be.
What really matters is the total amount of alcohol you consume, how quickly you drink it, whether you eat food and stay hydrated, and individual factors like your genetics and body composition. The type of alcohol may play a small role due to congener content, but drinking order simply isn’t a significant factor.
The best way to avoid a hangover is to drink in moderation, stay hydrated, eat before and during drinking, pace yourself, and allow adequate time for rest and recovery. If you choose to drink, make informed decisions based on science rather than myths and rhymes.
By understanding the real factors that contribute to hangovers, you can make better choices about alcohol consumption and potentially reduce the unpleasant after-effects. Remember, the only guaranteed way to avoid a hangover is to abstain from drinking alcohol altogether.
