You just woke up with a pounding headache to find that a friend has posted an embarrassing video of you singing a drunken rendition of “Sweet Caroline” at the local karaoke bar, and you’re not sure whether to laugh or cry. Getting up on a stage is not in your playbook, especially when singing is involved. “Do I really sound like that?” you wonder. And more importantly, “Why don’t I remember this?”
Unfortunately, lapses in memory and personality changes are a common part of booze-filled evenings. They can lead to innocent, albeit embarrassing, stage performances but also to more dangerous behaviors that can wreak havoc on our life.
In today’s blog post, we’ll explore the connection between alcohol use, memory, and behavior changes, and how these impact our health, relationships, and well-being.
To fully understand blackouts, we have to understand how alcohol affects our cognitive function. Alcohol is a depressant, which means it slows down all the messengers (neurotransmitters) from our brain to the rest of our body. The more we drink, the more it impairs everything from our movements to our speech to our very consciousness.
So, do you know what you're doing when blackout drunk? That’s a lot like asking about a tree falling in a forest. Alcohol directly targets the hippocampus, the primary structure in the brain responsible for memory. Excessive drinking disrupts the memory-making process, leading to the phenomenon of alcohol-induced blackouts. You may know what you’re doing in the moment, but you won’t have any memory of it the next morning.
Distinct from passing out, alcohol blackouts are when we remain conscious but our brain fails to hit the “record” button. As a result, we often find large gaps in our memory from when we were intoxicated.
So, what does blacking out feel like? It’s hard to say exactly given that most people don’t remember it, but from what we know about the general effects of alcohol, suffice it to say it’s a painful, confusing journey. The only tangible feeling is what comes the next day: you may experience one of two types of blackout:

In addition to blackouts, short-term and long-term personality changes are another common side effect of excessive drinking.
You know how tight-lipped Uncle Joe gets super chatty when he drinks? Or happy Aunt Jody starts sobbing uncontrollably? Or perhaps you’ve heard someone described as an “angry drunk.” These are just a few examples of short-term personality changes brought on by alcohol. However, it’s not so much that their personality changes as it is that their normal filters and barriers come down, revealing other facets of their personalities. Could that be why you got up on the karaoke stage? Do you secretly seek the limelight?
While short-term personality changes may make for embarrassing (and sometimes amusing) anecdotes, a repeated pattern of over-imbibing can lead to alcohol use disorder (AUD), which can alter our brain structure and chemistry, leading to lasting personality changes. Studies show, for example, that the more we drink, the more likely we are to struggle with anxiety and depression symptoms, which can significantly affect our mood.
Whether it’s an aunt who gets a little weepy when she drinks or a friend who is forever changed due to chronic misuse, it’s easy to see how alcohol can alter personalities and impact our lives. Let’s take a closer look at the possible outcomes.
The potential domino effect of drinking to the point of blacking out is nearly infinite. Every risk of normal drinking is present but to a higher degree:
As they say in physics, “Every action has an equal and opposite reaction.” The same applies to drinking: every sip we take can increase our risk of unintended consequences. The good news is that we can change our drinking habits, no matter how bad they may have gotten, and likewise reverse alcohol’s effects on our brain chemistry.
If you’re ready to kick alcohol blackouts out of your life, there are options. There is a whole support network of people at Reframe eager and willing to help you quit or cut back on drinking and live a healthier, happier, safer life. If you’re not ready to take that step, there are some things you can start to do on your own.
To start you on the right track, let’s explore some ways to prevent and/or manage drinking habits to reduce the risk of alcohol blackouts and personality changes:
As you put in the effort to prevent and manage your drinking habits, you can avoid blackouts and start to feel more like yourself again.
Alcohol has short-term and long-term effects on every part of our body, especially our brain. Heavy drinking can lead to blackouts, and chronic misuse can lead to personality changes. Both of these can lead to numerous negative outcomes in our personal and professional lives. But there is hope! With a little determination and help from our friends, family, and resources like Reframe, we can take control of our lives and feel more present again.
1. What does blacking out feel like?
Due to the nature of alcohol-induced blackouts, most of the signs of a blackout don’t appear until the alcohol wears off and we can’t remember what we said or did while we were drinking. A person may carry on conversations and appear relatively normal, albeit drunk, while blacked out.
2. Do you know what you’re doing when blackout drunk?
You may know, or think you know, what you’re doing in the moment, but you won’t have any recollection of it afterward because the alcohol interferes with the brain’s ability to create short-term memories.
3. How do you avoid alcohol blackouts and personality changes?
You can avoid alcohol blackouts and personality changes by drinking moderately or abstaining altogether.
4. What causes violent blackouts?
Alcohol affects each of us differently, but it is known to interfere with impulse control and inhibition. It is also known to cause irritability, anxiety, and/or paranoia. In some people, this mix can lead to violent encounters if they drink too much.
