I drink two pots of coffee a day, minimum. I have to have decaf these days because, the caffiene was kicking my ass. I suffered from caffiene intoxication, yes there really is such a thing, see DSM IV. Anyway, after a ceratain age I guess, you can take as much & you get all jacked up like a "clucker" & you feel like you're gonna have a heart attack or something. It's crazy. Anyway, since were are on the topic of piss pumps, I have to say that I only tend to piss a lot until the fist pot after that I'm good to go.
