My mom can stay up talking to herself ALL night long! She will be angry and yelling at someone, then cry for hours - sometimes giggle here and there and remain awake all the next day! The crying scares me because of the mucus she creates and I'm afraid she will choke. A few days ago I got a sleep aid from the nurse and gave her one at 7pm, she was still awake at 1am that night. Does anyone else experience this? Sometimes she will even sleep all the next day and into the night.
