  1. Caffeine is a drug/stimulant and just like with any other “feel good” drug, your body builds a tolerance to it. You can increase the amount you take in but eventually you will become tolerant to that also.

  2. There are a lot of answers on Quora you will find about adenosine receptors that bond with caffeine to keep you awake. I have a counter theory to this claim which makes me think coffee does not really keep anyone awake.
    What makes one sleepy is the devoid oxygen supply in the brain. As a result, when you are sleepy you yawn, drawing in as much oxygen that your brain cells need to keep you awake. This is an autonomous reflex action coming from the brain. So to keep oneself awake, you need a source that supplies oxygen to your grey cells to keep them going. Logically speaking, we all agree with this argument that cells need oxygen to stay alive.
    We all know, coffee is a great source of anti-oxidants, a substance which inhibits oxidation. The more coffee you drink, the more oxygen molecules you are using up, gradually decreasing the amount of oxygen needed for your brain cells to function normally. This makes you sleepy. So, if all this makes sense, coffee doesn’t really keep anyone awake. Your question seems credible. Correct me if I an wrong, anyone.
