Marc Lewis, neuroscientist and addiction researcher, and Cece Sykes, clinical psychologist and IFS trainer, discuss addiction as an adaptive response rather than a disease. They explore internal polarizations between critical and escape-seeking parts. They unpack neuroscience links to Internal Family Systems, the role of compassion, how therapy reshapes patterns, and practical ways to access calm, curious self-energy.
