Drano as poison? That's a first for me. You are going to feel it right away in your stomach and intestines before it can kill you. Drano is corrosive. Whatever happened to Drano crystals in the can? It was fun to use. Prolly too many idiots were getting hurt using it. Drano in the can was basically lye. Sodium hydroxide.
This murderous wife should have put eye drops in what hubs was drinking. I hear they are poisonous.
