Our household's immutable laws of analgesics:

1. Whatever my analgesic of choice for a given form of pain, in a cluttered medicine closet at 2:30 a.m. I  will be able to find every one except that.one.
2. However large a bottle of my chosen analgesic I may have purchased, and however rarely I personally need to take it, my family members will have completely consumed and not replaced it when I finally need it.
