Decoding Craving Through the Science of Habit

It was the fifth retail store I checked.

I glanced through the cold drink section, shook my head, and refused to settle for a Cherry Coke or sparkling tea.

This is my routine in an airport -- I would work through every single retail store from gate A1 to G14, determined to find the “most interesting” non-alcoholic drink. (My favorites are those exotic adaptogenic drinks).

Why am I routinely dragging my luggage and my husband through the entire airport?

Here is my little secret: Despite being a therapist turned sobriety guide, from time to time, I still deal with my own uninvited guest—craving—especially in an airport.

What an odd place to have a craving, you might think. Well, not really, if you know how craving works.

What Triggers a Drinking Craving After You’ve Quit

One fascinating mechanism in the human brain is something called the habit loop. When a behavior—whether mental or physical—is repeated often enough, the brain forms an automatic loop. In this loop, a cue triggers a craving for a reward, which then drives us to perform the behavior that delivers that reward.

This system exists to help us conserve energy and operate efficiently in everyday life. Craving, while disturbing and inconvenient around an unwanted behavior like drinking, is the driving force that fuels the habit loops. And here is how it works:

What the Habit Loop Teaches Us About Drinking Triggers

The habit loop is made up of three elements: cue, routine, and reward.

The cue is a signal—something that tells our brain it’s time to go into automatic mode and run a familiar pattern of behavior we call a habit. Through repetition, the brain learns to associate certain situations, objects, sensations, or emotions with a routine that leads to a specific reward.

For example, someone might associate 3 p.m. with having a donut. And when the clock hits 3, the craving for a sugar boost kicks in and drives them to walk to the break room.

In my case, after years of traveling, my brain learned to associate the airport with one thing: “Time to get tipsy before the boarding.”

When we’re dealing with unwanted habits, the cue is often called a trigger—something internal or external that reminds us of drinking. That trigger can activate a strong desire for the reward we used to get from alcohol—what we call a craving. And that craving is often followed by an urge, which is that intense impulse to reach for a drink.

4 Types of Triggers That Can Reignite Your Craving to Drink

A trigger can be anything your brain has learned to associate with drinking in the past.

Some triggers are external—like places, people, or events. Others are internal—emotional states, physical sensations, or even certain thoughts.

Some are obvious: a bar, the clink of ice in a glass, the smell of beer. Others are more subtle: a tight chest, that restless feeling at 5 p.m., or an emotion you’ve long numbed with a drink.

Many people—myself included—find it easier to work with cravings when we sort them into categories.

Situational Triggers. These include certain people, places, events, or even dynamics you associate with drinking. It could be:

• A friend you always drink with
• A networking event where you usually have a glass in hand
• A tense conversation you used to buffer with a buzz
• Or—like me—those jittery pre-flight moments at the airport, when your brain whispers: “It’s time to get tipsy.”

Emotional Triggers. These are internal states—like stress, anxiety, or loneliness. But emotional triggers aren’t always negative. Sometimes, we learn to associate positive feelings with drinking too—like excitement, celebration, or a sense of accomplishment. It could be:

• The lingering stress after a long workday
• The racing thoughts that just won’t leave you alone
• The holiday blues that hit unexpectedly
• Or that post-project high, where you feel accomplished and want a “reward”

Sensory Triggers. These are physical sensations or sensory cues—like smells, sights, or body discomfort—that your brain has learned to connect with drinking. It could be:

• The smell of wine or the sound of a can opener
• A mild headache you used to “fix” with a cold beer
• Feeling tired or run down
• Or even simple thirst—many people unconsciously associate alcohol with quenching thirst because it’s a liquid, even though it’s actually dehydrating

Internal Triggers. Internal triggers are thoughts or memories that activate a craving—often without any external cue. It could be:

• Negative self-talk like: “I always mess this up,” or “What’s the point? I’ll never change.”
• Intrusive thoughts that create overwhelm or anxiety
• Memories of past drinking that are romanticized—like remembering how relaxing that first glass felt
• Or even a thought like: “I deserve something for getting through this day.”

What to Do When You Crave a Drink

The first step to effectively managing cravings is to uncover your personal drinking cues—and how alcohol once served you.

At Sober Curiosity, we believe that truly breaking free from alcohol’s hold—and building a thriving, alcohol-free life—takes more than just “stop drinking.” It asks us to understand why we were drinking in the first place, and to discover new, alcohol-free actions that serve the same purpose alcohol once did, whether that’s managing boredom, unwinding after work, or feeling more connected in social settings.

That’s why we advise a four-pillar system to create sustainable change:

• Value: uncovering your whys behind choosing to drink less

• Belief: changing the story you’ve been told about alcohol and yourself

• Action: breaking the drinking pattern and replacing alcohol with more empowering options

• Result: embracing the learning process—and learning how to turn setbacks into stepping stones

Learning to manage craving lives inside the Action pillar. It asks us to pause when a craving hits, to interrupt the automatic habit loop, and to get curious: What am I really craving right now? Because often, it’s not alcohol; it’s relief, connection, comfort, or escape that we really crave. Craving invites us to meet those needs in new, more empowered ways.

Building a thriving alcohol-free life takes more than white-knuckling. It takes the right strategy and the right focus at the right stage.
