Alcohol is a depressant that affects the central nervous system (CNS). Once metabolized, the alcohol transports to the brain’s gamma-aminobutyric acid (GABA) receptors. The GABA is the part of the brain that lets you feel pleasure and euphoria.
When alcohol affects the GABA, you can experience increased confidence, social ease, and libido. The increase in confidence and loss of self-control is how alcohol can change your personality when you get drunk.
Knowing how alcohol changes your personality can help you identify a drinking problem. It can also help you look forward to living and maintaining a sober life.

Alcohol affects everyone differently. Because of this, there are different types of alcoholics and drunk personalities.
According to a study, four types of drunk personalities exist.2 These include:
These people are agreeable when sober and remain agreeable when drunk. Their levels of conscientiousness and intellect reduce only to a small extent when they are intoxicated.
This category includes those who behave roughly the same when drunk as they do sober. They maintain their average level personality metrics even when intoxicated, with no significant fluctuations in their levels of intellect and self-discipline as compared to other drinkers.
These people show drastic changes in their drunken behavior, with significant decreases in agreeableness, intellect, and conscientiousness when intoxicated.
They’re typically less responsible, less intellectual, and more hostile when drunk compared to when they’re sober. Their personality change is more apparent when compared to others.
These people become far less conscientious after drinking. They’re typically introverted when sober but are the life of the party when intoxicated.
Unlike the different drunk personalities, these types refer to how a person reacts to the effects of alcohol. For example, people who are Mary Poppins can also be a happy drunk, and Mr. Hyde can be an angry or reckless drunk.
Here are some of the ways alcohol may affect your personality when you’re drunk.
A common side effect for some drunks is becoming easily upset and highly reactive to imagined threats or minor inconveniences. Alcohol can affect how you assess emotional or physical threats, increasing aggression.
This side effect explains why an angry drunk quickly enters conflicts when intoxicated—one of the many potential alcohol-related consequences. They may also become paranoid about certain situations.
People struggling with alcohol addiction are often angry drunks. Once the alcohol wears off, you may regret your actions; this is called hangover anxiety.
During the early stages of drinking, many experience euphoria. This state of slight intoxication is sometimes called being ‘tipsy.’ Some people maintain this state of happiness regardless of how much they drink.
Happy drunks may begin to slur their words or become less coordinated, but their joyful mood remains. This reaction is likely due to how alcohol affects anxiety levels, making people forget their concerns.
However, in some cases, happy drunks may feel the opposite the morning after. As long as you don’t regularly rely on alcohol to reduce anxiety, there’s nothing wrong with being a ‘happy drunk.’
People who down a lot of alcohol or “binge drink” can sometimes experience memory loss. Most people refer to this experience as blacking out.
Those who can’t stop or control their drinking may black out more often than others. Intoxication can lead to risky behaviors and poor decision-making; because of this, blackouts can be dangerous. If you’re a blackout drunk, you should avoid excessive drinking.
Blacking out at parties is common among college student parties. It’s also an early sign of an alcohol use disorder (AUD).
A sloppy drunk can engage in risky behavior and become overly sexual after drinking. This type of drunk is also more likely to do drugs, drive under the influence, or cause accidents.
This reaction happens because of how alcohol can lower inhibitions. Even if you don’t want to engage in these behaviors, excessive drinking can shift your ability to control your actions and make rational decisions.
Some people may become more expressive and emotive when drunk, even if they’re quiet or reserved. Affectionate drunks are typically more loving when drunk.
This change typically happens because alcohol can make you more sensitive or emotional. Although there’s nothing wrong with being affectionate with people you know, this can be dangerous around the company of strangers.
Some people are prone to recklessness when they’re drunk. These types will act impulsively and dangerously because of intoxication.
Unlike sloppy drunks, who may cause problems accidentally, reckless drunks may do so on purpose. They can act in dangerous ways, like drunk driving or diving off a roof into a swimming pool.
Some people never seem to act drunk, no matter how much they drink; this is called a “secret drunk.” A secret drunk may have a high tolerance for alcohol. However, this may be due to genetics.
Some genes make some more sensitive to alcohol, while others may make some less vulnerable to alcohol’s effects. However, high tolerance to alcohol isn’t necessarily a positive thing.
People with a high tolerance for alcohol may need to consume more significant amounts to experience the same effects. As a result, they may drink excessively or develop an alcohol addiction.
