    Caffeine Was My Gateway Drug

    Caffeine did not cause anything. It taught me that the brain I woke up with wasn't the brain I had to keep, and that lesson generalised. A personal account with the pharmacology attached, including why three tablespoons of grounds per cup felt almost identical to low dose amphetamine.
