If you are unaware that tea can have a massive effect as a stimulant, in the right quantities, then you just simply don't know enough about tea (which is a vast topic), neither have you experienced it first hand. I can guide you to generating this effect if you are interested. Let me know
I'll quote Lyle: "Tea also contains caffeine (but tends to lack the stimulant effects of caffeine due to a compound called theanine which has a calming effect) "
I'm interested, sure. Discuss.
