Your brain processes pleasure and pain in the same place, and it treats them like opposite ends of a balance. Feel pleasure, and dopamine floods the reward pathway, tipping the scale one way. But the balance hates staying tipped. It wants to sit level, so every swing toward pleasure triggers an automatic correction that pulls it back and, thanks to momentum, pushes it an equal distance into pain. Lembke pictures the correction as little gremlins hopping onto the pain side to cancel out the weight of pleasure. That after-reaction is why the second chocolate satisfies less than the first, and why the moment you crave one more is really the balance already dropping toward pain.
