Q. A 76 year-old man is having trouble sleeping. He has tried various sleep aids before, including zolpidem (trade name: Ambien), and eszopiclone (trade name: Lunesta), but they always made him feel very hung over in the morning and, worse yet, made him feel strange at night. He is done with these "crazy medicines" and just wants something simple to help put him to sleep. He doesn't have much to get up for in the morning and is fine with feeling a little foggy until his morning coffee. He just doesn't want to go "nuts" from one of these medications. You tell him you have a medication in mind that is an old-line medication but is effective. You warn him that it may cause some dry mouth and dry eyes. Which of the following would also potentially accompany these side effects?
