Waklert 150 mg can help you stay awake and focused for 10 to 14 hours, occasionally a little longer. If taken in the morning, most individuals experience peak alertness around midday, with most people feeling its effects within 1-2 hours. It can considerably lessen tiredness, but it won't actually keep you up all the time. It is recommended to take it in the morning because taking it late in the day might interfere with sleep at night. Your experience may be different due to variations in effects and duration.
