Insomnia Disorder

A 77-year-old overweight woman with hypertension and arthritis reports that she has had trouble sleeping for as long as I can remember. She has taken hypnotic medications nightly for almost 50 years; her medication was recently switched from lorazepam (1 mg), which had been successful, to trazodone (25 mg) by her primary care physician, who was concerned about her use of the former. She spends 9 hours in bed, from 11 p.m. to 8 a.m. She has only occasional difficulty falling asleep, but she awakens two to three times per night to urinate and lies in bed for over an hour at those times, just worrying. How should her case be managed?
