>>2782898Yeah. Pretty much every "good" part of coffee has been scientifically proven to merely be the drinker coming back to normal levels by feeding into a need for coffee.
Basically, whenever people need coffee to wake up or concentrate that isn't something that puts them in a more focused or heightened state than the average non-coffee drinker, rather it just returns them to normal.
Severe caffeine withdrawal can have quite serious effects.
