Great suggestion!
My mother had low vision and was the same way. If mom could find an empty spot in the refrigerator or the pantry she just kept putting stuff in. She was amazed at how much easier her day to day routine was when she allowed me to do a purge and quick inspection on marketing day.
Yep, she was the same way with medications. I found stuff that was up to 5 years old. Nobody else in the family wanted to throw it away because they were afraid she would get mad at them. She was/is really bad about self-medicating. Right before I left, I went through all the meds, put everything that was expired or she was no longer supposed to take in a big plastic baggie, gave it to the visiting nurse to dispose of, and told the rest of the family to blame it on me if they needed to because I wouldn't be there to "face the music." She never said a word to me when we talked on the phone afterward. I don't think she even missed it cause nobody else said anything to me either when we talked.
