The Scottish Recovery Consortium has developed a self-help resource called the Scottish Recovery Workbook. It supports 12-step meetings, SMART recovery meetings, recovery communities and faith groups that contribute to recovery.
The Scottish Recovery Workbook will support you if your goal is to abstain from alcohol and drugs. However, the workbook also contains very useful and practical tools that would be helpful in changing your behaviour, even if your goal is not abstinence. There are also recovery stories from people who have lived experience.
