Don't worry, you won't die, lol. If it was that poisonous, you wouldn't put it in your mouth in the first place. I saw on tv how a lot of homeless people drink listerine to get high, lol. They didn't die from it. I suggest that you stop using that crap, and buy mouthwash products from a health-food store. I personally use "JASON" mouthwash products. They have fluoride and non-fluoride ones (i buy non-fluoride). The ingredients they use are the best.
