Your brain makes more receptors when there is more of the applicable agent around.
So, if you have morning level of Adosyne + 120 mg caffeine in your blood in the morning, and afternoon levels of Adosyne + 80 mg caffeine + residual in the afternoon, that is going to keep the “need for receptors” high throughout the day.
Then, also, having caffeine in your system as you sleep will also keep more receptors around until the morning than happens for people without caffeine in their system.
Adosyne builds up over the course of the day.

That helps me better see what you mean—thanks.
