My 96 year old father lives with me. He is slowly declining mentally as well as physically. At night, when I am ready to sleep, he babbles...loudly. He calls out for my deceased mother and his deceased sister. He thinks he needs to leave. He yells. He seems to be caught between dream stage and awake stage. This lasts for about an hour and a half before he doses off only to begin again... loudly...in a couple of hours. Has anyone had any luck using melatonin for their elderly loved ones? If so, what dosage? Help! I am so sleep starved, I can't remember my name! Thank you for any help!
