Good point. I drink about 1-3 cups a day, and wonder sometimes how dependent my energy and mood is on caffeine. I _think_ I feel groggy without a morning cup, but I'm too lazy or unconcerned to track how I feel, how much I drink and factors like sleep very closely. I'd love to read more about studies on this, I'm sure they're out there.
