Although her mood is good and she enjoys being around people, she seems to require an inordinate amount of reassurance from others. She is also reluctant to make even minor decisions without input from her husband. On evenings when he works late, she calls frequently "just to touch bases."

His lungs are clear to auscultation and percussion although he reports some discomfort with deep inspiration. Laboratory studies are remarkable for a blood alcohol level of 0.05 % (50 mg/dl). When asked about this, the patient reports that he always enjoyed “a night out with the boys” but rarely drank during the week.
