> If you are heavily medicating with caffeine, then that can be a signal. I was using Pseudoephedrine and caffeine to self medicate and stabilise my moods and behaviours. That was before I got prescribed Ritalin.

Does tea count? I dislike coffee; I only drink some when I absolutely need to stay awake (caffeine in energy drinks is another thing, this I like). But ever since I was a kid, I've been drinking ridiculous amounts of black teas every day, on the order of 10-15 cups. I ask because I keep hearing that the stuff in tea is pretty much the same thing as caffeine...
