It's funny, but I've never noticed a caffeine effect from tea. No matter how much I drink. Coffee, on the other hand, can have me feeling bouncy and downright high after a single cup. What could explain this? Do I just suck at steeping my tea long enough, or something?

Anyway, I agree with your approach. Caffeine is physiologically addictive, and if you use it often enough, it stops being a fun bonus and becomes something you need just to feel normal, and that's a ridiculous state of affairs.
