A 45-year-old woman presents to a dual-diagnosis outpatient clinic for psychiatric evaluation. She reports an increase in her alcohol consumption over the past week due to frustration with her colleagues and partner.
Over the past two weeks, she has been more productive at work, leading to conflicts with her colleagues whom she accuses of holding her back. She frequently argues with her partner, who accuses her of being too friendly with male colleagues.
She has experienced similar episodes in the past, lasting about a month and occurring twice a year. During these times, she drinks more alcohol than usual as she finds it difficult to relax and fall asleep in the evenings. She is concerned that her alcohol consumption could have negative health consequences if this pattern continues.
