I use a lot of caffeine, (tea, caffeine pills, coffee)
Is caffeine giving me an edge or is it all in my mind? I *feel* more productive with use of caffeine but i'm not sure if this is an illusion or reality.
also, i have no data to support my claim, that is why i'm unsure if caffeine is actually productivity boosting or illusion.
