The point of no return. That point when your past your limit of consciousness late at night, but you are still asleep. When you're so sleepy you are in a state of euphoria, kind of like being high. Best results exhibited at 2-3 a.m. with a friend who is also sleepy high. (Not responsible for any damges done to readers or reader's houses.)
