Companion Care Needed

My 85-year-old husband has dementia. I periodically go to the Bay Area to see my family. He has VA caregivers for a few hours during the day. In the evening, he tends to get upset if he can' t get to sleep within an hour or so, and in the past, he has taken overdoses of his sleep medications and ended up in the ER. So, I keep his bedtime medications locked up. I need somone to check in on his and hand him that evening's medication. It' s basically a one hour visit between 7:30 to 8:30 or 7 p.m. to 8 p.m.
