INTRODUCTION: Interest in managing alcohol-related risks through temporary abstinence challenges has grown significantly. Studies on abstinence challenges in the general population show improvements in for example mental health, blood pressure, insulin resistance and alcohol consumption, but studies in clinical samples are lacking, including qualitative research on patients' perspectives on such a clinical intervention. This study aimed to explore the patients' experiences of a sober month before initiating psychological treatment for controlled drinking.

METHODS: A qualitative interview study (n = 14) was conducted at a specialised addiction clinic in Stockholm, Sweden. Participants were recruited within a randomised controlled trial examining a sober month as an adjunct to psychological treatment for controlled drinking. Data were analysed with applied thematic analysis.

RESULTS: Four themes were identified: (i) Breaking the cycle of habitual drinking; (ii) Regaining control; (iii) A sober month made abstinence a more prominent part of goals; and (iv) A failed attempt at sobriety as a setback to change. A sober month was perceived as positive for most patients and became a challenge that increased the sense of control and perceived ability to abstain. The benefits of the sober month made participants consider more restrictive goals or abstinence over time. Not being able to abstain made participants less motivated and reconsidered controlled drinking as their goal.

DISCUSSION AND CONCLUSIONS: Having a sober month can increase awareness of the ability to abstain and guide patients toward lower consumption goals. To reduce the risks of negative consequences, it is important to identify and support those who do not manage to abstain.
