Need crazy amounts of caffeine to "relax"?!

that is not excessive. Buy yourself a nice espresso machine and make your first cup at home and then give up the nasty take out stuff. You might get headaches if you quit caffeine all at once. don't wander the world with a cuppa joe in your hand. Don't forget to breathe!

I know what you mean, I've had the exact same experience. I figured out I was basically making my own ADHD medicine. But now your body is addicted, so it needs the coffee just to stave off the withdrawls. Only drink when you start getting shaky if you want to cut down.
