    Narcolepsy and associated sleep disorders are treated with the wakefulness-promoting drug modafinil. It functions by affecting neurotransmitters in the brain that are involved in alertness, namely dopamine, norepinephrine, and histamine, without having the same effects as traditional stimulants. By preventing its reuptake, modafinil raises extracellular dopamine, promoting prolonged focus and decreased weariness. Additionally, it influences circadian rhythm and the hypothalamus, which helps maintain stable sleep-wake cycles. Many people report feeling less jittery and having better attention. Modafinil is found in the branded formulation Modvigil 200, which is usually recommended under medical supervision for certain disorders exclusively. It should not be taken without expert guidance or counsel because it is not a cure.
