Drink alcohol and listerine. Will I still get in trouble if my parents know?

If they love you. If your parents love you they will be angry and punish you accordingly if they find out. Listerine is dangerous to drink and if you are not of legal age, alcohol is dangerous too.
You may get sick. Drinking alcohol at such a young age is already bad by itself, drinking listerine is not very smart because it may cause you more stomach and intestinal irritation and other side effects and complications. This looks like an addiction and you need help, please talk to your parents, they are the one who care the most. Peace.
