    The way caffeine works is that it allows the body to release energy reserves that it usually “locks” away from you.

    I thought it just blocked the receptors for the chemicals that made us feel sleepy, not tapped into some hidden energy.

      That’s basically the same thing. When you feel sleepy, you aren’t at the end of your reserves. Your body tells you that you are sleepy at a time when you still have reserves.

      Blocking these receptors doesn’t tap into any magic hidden energy, it just stops your body from telling you that you are running on fumes. Thus it allows you to go farther into your reserves. In extreme cases to the point where you collapse, because you really don’t have any reserves left.

      Edit: Just to be clear, going into your reserves is not a good or healthy thing. It’s not some magical potential unlocker or something, but it’s running your body under circumstances it’s not made for. If you use caffeine when you really should be sleeping, that’s short-term ok, but can lead to some serious consequences in the long term.

        Your last sentence is spot on, and I’m paying for it now.

        Once I’ve weaned off of real coffee, it’ll be one instant a day, maximum. Sick of the cycle. It’s caused chronic fatigue - like symptoms and they’re horrible.

          If you want best effects, do no more than 2x per week, only when you actually urgently need a boost. Otherwise the one instant per day won’t have an effect either.
