Ah, thanks for the clarification. My understanding about the effects of caffeine is not based on anything other than hear-say from people who seemed to have done their research better than I have, but from what I did hear, caffeine on an empty stomach may have opposite the intended effects, making you actually more confused instead of boosting focus.
Anecdotally after hearing this myself, I have tried to make it a point to take coffee less often when on an empty stomach, and it does seem to help with focus-depletion.
