How does Tylenol 3 get you high?

No. It can kill you, though. When you take a high dosage of Tylenol, your liver cannot process it, and therefore shuts down. The antidote is called Mucamyst, and the taste is extremely unpleasant. If you don't take it within somewhere around 24 hours, during which time if you try to eat you will vomit and feel pretty much dead anyway, your body will slowly kill itself over the course of two weeks. Seriously, don't even think about trying this. If you're going to drink cough syrup, think about how desperate that is, but if you're going to do it anyway, read the ingredients. If "acetaminophen" is one of the ingredients, do not take it. Acetaminophen is the generic for Tylenol, and if you take the required dose to get high off cough syrup, you'll also take enough Tylenol to either kill yourself or cause severe liver damage.
