Wanna hear something cool about caffeine. Caffeine is an adenosine antagonist. Adenosine builds up in your body the longer you’re awake - it’s what makes you feel fatigued. Caffeine blocks adenosine receptors, but when caffeine wears off, the adenosine that’s still around binds to that receptor and you crash (Afternoon crash). So the way around this is to not ingest caffeine for the first 90 mins - 2 hours of waking. So the adenosine can dissipate naturally and no afternoon crash. Also.. don’t drink caffeine 12 hours before bed, the quarter life of caffeine is 12 hours. Meaning if you have 200 mg of caffeine at noon, 50mg will be circulating in ur brain - effecting the quality of your sleep.
