A study was conducted by the University of Barcelona and published in 2008. The Stanford Sleepiness Scale was used to asses the decrease in somnolence induced by caffeine pre-consumption, post 10 min, post 20 min, and post 30 min. Scores for "subjective activation" were also recorded at the same intervals. Many previous studies assessed the effects of ...
