RecruitingBehavioural interventionWellness, Alcohol, Vitals, and EmotionsThe goal of this clinical trial is to examine the effects of mindfulness based relapse prevention on self-regulation overtime and drinking in daily life through the use of wearable heart rate sensors during mindfulness groups and answering assessment questions 3 times per day during the course of treatment. The main questions that it aims to answer are: 1. What changes in self-regulation as measured through heart rate variability are observed during a mindfulness intervention and how do those self-regulatory changes affect drinking after treatment? 2. How do changes in heart rate variability affect drinking, craving, and negative affectivity in daily life? Participants will: 1. Answer questions related to their mood and drinking behaviors. 2. Wear their sensors during an 8-week treatment period with 1 group per week. 3. Answer questions 3 times a day during the treatment period. 4.) Return their sensors via a pre-stamped package and answer questions about their mood and drinking behaviors 3- and 6-months after the mindfulness groups end.
