The best type of therapy for alcohol addiction is Cognitive Behavioural Therapy (CBT). CBT is an evidence-based approach to treatment that helps people identify and change negative thought patterns and behaviours related to their addiction. It encourages those in recovery to recognize the connection between their thoughts, feelings, and behaviours, and helps them develop healthier coping strategies. CBT can be used to help people understand the underlying causes of their addiction, as well as develop coping skills to manage cravings and triggers. It is also used to improve communication in relationships, manage stress, and address any unresolved issues or traumas that may have contributed to the development of an addiction.
