Modafinil, the active component of Modalert 200, is mainly used to promote wakefulness and alertness in order to treat disorders such as narcolepsy, sleep apnea, and shift work sleep disorder. Because of its stimulating properties, some users report feeling slightly happier, even though it is not particularly made to do so. A stronger sense of productivity, more attention, and less exhaustion might be the cause of this. Modafinil does not, however, have antidepressant properties, and individual differences may exist in how it affects mood. A healthcare professional should be consulted if you're dealing with ongoing mood problems. To guarantee its safe and efficient usage, Modalert 200 should only be used under medical supervision.
