What are the risks of a dopamine fast for people with co-occurring ADHD and anxiety?

First, you can't actually "fast" from dopamine. It's not like skipping lunch. It's a neurotransmitter, something your brain makes all the time. If it stopped, you’d have problems much bigger than Twitter addiction—Parkinson's disease is caused by a lack of dopamine.

The phrase "dopamine fast" is just a catchy, science-ish rebrand of an old therapy technique: stimulus control. The idea, which came from Dr. Cameron Sepah, isn't about lowering your dopamine. It's about taking a break from easy, cheap highs—endless scrolling, gaming, online shopping—to get a handle on impulsive behaviors.

For most people, stepping away from the phone is probably a good idea. But for someone with both ADHD and anxiety, the game is different. The wiring in your brain just isn't the same.

The ADHD and Anxiety Brain

ADHD is a story about dopamine. Brains with ADHD often have more dopamine transporters, which are little vacuums that suck the chemical up too quickly. The result is a lower baseline level of dopamine, which messes with focus, motivation, and emotional control. This is why many people with ADHD are drawn to high-stimulation activities; they're subconsciously trying to push their dopamine up to a level where they can function.

Anxiety's relationship with dopamine is more complicated, but low levels can make anxiety and mood swings worse. The brain’s reward system runs on dopamine, driving you toward what feels good and away from what doesn't. When that system is unstable, it can feed both the reward-seeking of ADHD and the avoidance of anxiety.

So what happens when you tell a brain that's already fighting to stay balanced to cut off its main sources of stimulation?

It usually doesn't go well.

Risk 1: Making Symptoms Worse

Forcing someone with ADHD and anxiety into a low-stimulation state is like taking a crutch from someone with a broken leg. The things they're "fasting" from might be the very tools they're using to manage.

Cut off those coping mechanisms, and things can get worse. Anxiety can spike. Irritability goes up. The boredom can feel so overwhelming that it becomes impossible to focus on anything.

Risk 2: The Rebound

Extreme restriction almost always leads to a rebound. I tried a "digital detox" once, locking my phone in a timed safe for 24 hours. The first few hours were fine. Then the restlessness hit. By the next morning, the urge was so intense that when the timer finally clicked open, I fell into a five-hour scrolling vortex that left me feeling worse than before.

That's not a failure of willpower. It's what happens when you starve the brain of something it needs. It will overcompensate the second it gets the chance. For someone with ADHD, this just reinforces the all-or-nothing cycle they were trying to break in the first place.

A Better Approach

The goal isn't to eliminate everything, but to be more deliberate. It's not a fast; it's learning to build a better media diet. You don't stop eating, you just learn to choose things that actually nourish you.

1. Reduce, Don't Remove. Instead of banning video games, try setting a timer for 45 minutes of focused work first. Use an app to block distracting sites instead of relying on pure willpower.
2. Add the Good Stuff. Don't just focus on what you're cutting out. Think about what you can add. Exercise, time outside, music, or a real-world hobby are all better sources of dopamine.
3. Notice the Urge. The original idea was about recognizing your triggers. Next time you feel the pull to scroll, just pause for a second. What are you trying to get away from? Boredom? Stress? Just seeing the pattern is the first step.

The impulse behind the dopamine fast is a good one. It's smart to manage impulsive behavior. But for anyone with ADHD and anxiety, a rigid, all-or-nothing fast can trigger the very problems you want to solve. The real work isn't about fasting from a brain chemical, it's about figuring out how to live in a world of infinite distraction without letting it run your life.
