Modafinil is widely recognized as a powerful cognitive enhancer used to boost focus, alertness, and mental clarity. Originally developed to treat sleep disorders like narcolepsy and sleep apnea, it has gained popularity among students, professionals, and entrepreneurs seeking enhanced productivity and sharper thinking. Modafinil works by stimulating certain neurotransmitters in the brain, helping users stay awake and mentally active for extended periods without the jittery side effects associated with traditional stimulants.
