Caffeine Necklace

ion_dog's recommendation

The most widely consumed psychoactive substance in the world, caffeine causes a surge in norepinephrine, keeping us awake and alert. It also binds to adenosine receptors on the surface of cells ni the brain, reducing adenosine activity and increasing the neurotransmitter dopamine, causing a feeling of happiness and enjoyment. And, it increases serotonin levels, leading to a feeling of being at ease and content.
