A 79-year-old self-identified male presents to your pharmacy complaining of difficulty initiating sleep over the past 4-5 nights.  He complains of having an active mind once he lies down to go to sleep at night, and it may take him up to 90-120 minutes to fall asleep.  Once asleep, he sleeps well until morning without awakenings.  He has been drinking 3-4 alcoholic drinks prior to bedtime to help him fall asleep (which has only been partially helping). Which of the following is TRUE regarding treatment of his insomnia symptoms?
