Modvigil, containing modafinil, is primarily a wakefulness-promoting drug used to treat narcolepsy, sleep apnea, and shift work sleep disorder. It does not cure sleep deprivation but can temporarily improve alertness and reduce fatigue. It cannot replace actual sleep and should be used cautiously under medical supervision due to potential side effects like headache, insomnia, or anxiety. https://www.smartfinil.net/product/modvigil-200/
