Another factor which may or may not affect you depending on whether you drink coffee is adenosine receptors. Coffee blocks the adenosine (feel sleepy neuro Chem) receptors. Repeated caffeine intake makes your brain compensate by making more receptors. After a while of regular coffee use, when you wake up after sleeping, your body has not had caffeine in some hours and all of those adenosine receptors are free to be populated with adenosine. If you’ve ever quit coffee suddenly, you might have noticed an urge to just sleep constantly for multiple days until your body adjusts. I personally love Caffeine and coffee but have experienced this adenosine fatigue before which has caused me to take regular breaks from coffee and reduce my overall intake which leads to feeling way less groggy in the early wake up phases.
