So yes, I think it would be more informative to have a half life describing decay in some interesting functional measurement like heart rate rather than raw caffeine concentration because dose response curves are not linear. too much caffeine remedy reddit. Caffeine enters the bloodstream through the stomach and small intestine and can have a stimulating effect as soon as 15 minutes after it is consumed. Adults can clear caffeine from their system faster than any other age group. Dose-response curves are likely to be much more complicated and how the response decays could be even more complicated still, requiring many parameters to adequately characterize. #23 - Matthew Walker Ph.D - Author of "Why We Sleep: Unlocking the Power of Sleep and Dreams" 3.

Daily caffeine consumption amounts are out of control. Caffeinated beverages like coffee, tea, and soda can alter estrogen levels. By mixing caffeine and adrafinil you can experience similar or better results. Keep going downstream until you get to a physiological response you actually care about (eg heart rate, reaction time) and you end up with a "dose response curve".
