Sad. Child will grow up without her father. Let us not forget though, that we don't know when any of us will leave here. I doubt that he was planning on dying when he took the sleeping pills.
I don't take sleeping aids as I don't want to become dependent on them to get my zzz's. When I can't sleep, I turn on the television and lay down on the sofa with the lights off.
Eventually, the combination gets me relaxed so that even if I don't get more than three hours sleep at least I've rested.
