Comment: See if eliminating porn for 4 weeks helps you regain control
Julie Stewart, January 15, 2024
It’s an appealing concept: Stop addictive behaviors for a while — think social media, video games, gambling, porn, junk food, drugs, alcohol (dry January, anyone?) — to reset your brain’s reward circuitry, so you can feel great minus the bad habits.
People call it dopamine fasting, abstinence sampling, or dopamine detox. But is shutting off the rush of that feel-good neurotransmitter really the key to kicking addictions?
TikTok influencers and Silicon Valley execs seem to think so. But so do some physicians.
Prominent among the proponents is Anna Lembke, MD, professor of psychiatry at Stanford University School of Medicine and chief of the Stanford Addiction Medicine Dual Diagnosis Clinic. There, the dopamine fast is an early intervention framework for many of her patients.
“What we have seen in those patients is that not only does craving begin to subside in about 4 weeks, but that mood and anxiety and sleep and all these other parameters and markers of good mental health also improve,” Lembke said.
Any clinician, regardless of background, can adopt this framework, the Dopamine Nation author said during her talk at the American College of Lifestyle Medicine (ACLM) conference last fall. “There is this idea in medicine that we have to leave addiction to the Betty Ford Clinic or to an addiction psychiatrist,” she told the gathering. “But there’s so much that we can do, no matter what our training and no matter our treatment setting.”
But is dopamine fasting right for your patients? Some experts said it’s an oversimplified or even dangerous approach. Here’s what to know.
Dopamine and the Brain
From the prefrontal cortex — your brain’s control center — to the nucleus accumbens and ventral tegmental area located deep in your limbic system, dopamine bridges gaps between neurons to deliver critical messages about pleasure, reward, and motivation.
We all have a baseline level of dopamine. Substances and behaviors we like — everything from chocolate and sex to cocaine and amphetamines — increase dopamine firing.
“When we seek healthy rewards, like a good meal out in a restaurant or having a nice chat with friends, dopaminergic neurons fire, and dopamine is released,” said Birgitta Dresp, PhD, a cognitive psychologist and research director with the Centre National de la Recherche Scientifique in Paris. “That gives us a good feeling.”
But over time, with chronic exposure to hyperpleasurable stimuli, your brain adapts. Dopamine receptors downregulate and shrink, and your “hedonic setpoint,” or baseline happiness level, drops. You now need more of your favorite stimuli to feel as good as you did before.
This primitive brain wiring served evolutionary purposes, helping our ancestors relentlessly pursue scarce resources like food. But in our modern world full of easily accessible, novel, potent, and stimulating activities, our brains are constantly trying to compensate. Paradoxically, this constant “self-titillation” may be contributing to our national and global mental health crisis, Lembke suggested.
“Human activity has changed the world we live in,” said Lembke, “and now this ancient mechanistic structure has become a liability of sorts.”
The Dopamine Fast in Action
To reset this wiring, Lembke recommends a 4-week fast from a person’s “drug of choice.” But this isn’t the trendy tech-bro quick cure-all where you abstain from everything that brings you joy. It’s a targeted intervention usually aimed at one behavior or substance at a time. The fast allows a person to understand “the nature of the hijacked brain,” and breaking free motivates them to change habits long term, said Lembke.
Although the first 2 weeks are difficult, she finds that many patients feel better and more motivated after 4 weeks.
How do you identify patients who might benefit from a dopamine fast? Start with “how much” and proceed to “why.” Instead of asking how much of a substance or behavior they indulge in per week, which can be inaccurate, Lembke uses a “timeline follow-back” technique — how much yesterday, the day before that, and so on. This can lead to an “aha” moment when they see the week’s true total, she told the ACLM conference.
She also explores why they do it. Often patients say they are self-medicating or that the substance helps with their anxiety or depression. When people are compulsively continuing to use despite negative consequences, she might recommend a 4-week reset.
Important exceptions: Lembke does not recommend dopamine fasting to anyone who has repeatedly and unsuccessfully tried to quit a drug on their own nor anyone for whom withdrawal is life-threatening.
For people who can safely try the dopamine fast, she recommends “self-binding” strategies to help them stay the course. Consider the people, places, and things that encourage you to use, and try to avoid them. For example, delete your social media apps if you’re trying to detox from social media. Put physical distance between you and your phone. For foods and substances, keep them out of the house.
Lembke also recommends “hormesis,” painful but productive activities like exercise. Your brain’s system for pleasure and pain are closely related, so these activities affect reward circuitry.
“You’re intentionally doing things that are hard, which doesn’t initially release dopamine, in contrast to intoxicants, but you get a gradual increase that remains elevated even after that activity is stopped, which is a nice way to get dopamine indirectly,” she said.
If patients plan to resume their “drug of choice” after the dopamine fast, Lembke helps them plan how much they will consume and when. For some, this works. Others, unfortunately, go back to using as much or more than they did before. But in many cases, she said, patients feel better and find that their “drug of choice” wasn’t serving them as well as they thought. …
