Usually called the doctor. Or the caretaker.

I on occasion may have five drinks in a night, but it's a binge if I have them all at the same bar? (depending on the night and drinks, 5 will usually take me 5 to six hours to consume, unless one of the drinks is a good scotch, in which case it might be 7 or 8 hours).

If course, if a "sitting" means you don't get up to pee, I might have more sympathy for the definition.

Rate matters - so does effect.

As for the definition of binge, I thought the term implied an extended bout of drinking, with nasty consequences - ranging from raging headaches to missing an important engagement because you slept through it.
