I'd love for to investigate caffeine. At least in American society, coffee is the most utilized in office jobs and also seen as the most accepted.

Does this lead to a lack of scientific and corporate interest on the long term affects? What are the adverse affects on various job performance factors: quality of sleep, memory and attention, actual productivity vs perceived productivity?

Personally I'm an active drinker of caffeinated tea. And I feel less productive drinking it than when purely sober after a month of fasting in Ramadan. While this is a small sample size, and maybe not even correlated, I feel like year after year after re-introducing caffeine I lose productivity and eventually sleep.
