The case of a thirty-eight-year-old man with an adjustment disorder together with anxiety is described. The perception of his work overload led to consequences such as symptoms of anxiety, perception of inability to solve problems, difficulty disconnecting, and continuing in the present situation. Another consequence was a deterioration in his daily routine, in addition to excessive drinking. Cognitive behavioral therapy, a multicomponent treatment for anxiety (psycho-education, cognitive techniques, and physiological techniques deactivation), was applied, together with controlling his drinking program as to reduce alcohol consumption, and training in problem solving and time management to reduce his work overload and eliminate stress. At the end of the treatment, there was an improvement with his physiological arousal, especially in the decrease of anxiety regarding working environment and resolved drinking behavior. Intervention results which confirm the effectiveness of treatment are discussed.
