Did her husband know about the pills?
When Alice dropped all of the pills on the floor, did her caretaker or anyone in the family realize what she was doing? I don't think she'd have the presence of mind to clean them up. When Alec Baldwin asked "Do you still want to be here?" in the yogurt shop in the next scene, was he asking because they'd found the pills?
And when you tell a story, have a point. It makes it so much more interesting for the listener.
