After a short while of regular caffeine consumption, tolerance kicks in. My understanding is that the cognitive and focus boosts largely disappear in the sense that your new baseline is lower and your morning coffee simply raises you up to your original baseline.

This knowledge is what's kept me from becoming a regular coffee drinker; The awareness that I'll get a few weeks (?) of added productivity but will then simply start at a lower baseline makes me want to preserve my caffeine sensitivity for those days when I _really_ need a pick-me-up.
