Your medicine cabinet and linen closet are in your bathroom, so you're supposed to store your medicine there, right? Wrong. Most medicines need to be stored in dark, cool and dry places...not like a bathroom full of shower steam and heat. Store your medicine bottles in a tupperware container in a lower kitchen cabinet, a non-bathroom closet or under the bed. Chances are, you pay quite a bit for the stuff in your medicine cabinet -- don't let it all go bad from incorrect storage.
