The signs for needing a dopamin detox include being compelled towards behaviors you don't enjoy, experiencing a conflict in your brain between should do and impulsive behaviors, and finding activities pleasurable to others less enjoyable. If these signs align with constant dopamine-inducing activities, such as video games or social media, a detox may be necessary. To detox, it is essential to give the brain a minimum of two weeks without excessive dopamine to allow the receptors to regulate properly.
