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.

For tea to be awakening it's important to remove the leaves from the cup after a few minutes. If you leave the leaves in the tea other substances go into the tea that counteract the caffeine effect.

Do you have a citation for this claim?

At the moment I don't find a reputable english source however, I can however elaborate the argument a bit more:

Tea contains both caffeine and theanine. Theanine relaxes the body and reduces stress while coffeine does the opposite. If you brew the tea longer than the ratio of caffeine to theanine that gets released changes.

My understanding was that caffeine was dissolved almost immediately, on the first steep or two, and this was a standard recommendation for those who wish to cut down their caffeine consumption - throw out the first steep and drink the others. So the ratio could only be changing in theanine's favor, which doesn't sound like a bad thing.
