If I get prescribed antibiotics from the doctor, unless it's life threatening I store them in the cupboard. It's short term inconvenience, but when the apocalypse happens, zombie or otherwise, I'll be sitting on a trading goldmine.
@fesshole This is also smart, because it helps keep antibiotics usable for everyone by not making the bacteria resistant through overuse of antibiotics. I normally refuse to get antibiotics prescribed if not absolutely necessary. But sometimes I take home the ab in case things go south on a weekend. If it doesn't go south I just don't take them and have them on hand if needed on another weekend.
