Don't do it. You wouldn't be asking about what would happen to you if you didn't care a little bit about your well-being. Just don't do it. It's dangerous. It's a opioid and will help pain. Maybe if you take to much you might feel droits and if you get enough might pass out, slow and painful drug overdose, and other extreme consequences.
