Modvigil 200mg might result in unpleasant side effects and overstimulation. High blood pressure, jitteriness, restlessness, and a fast pulse are typical symptoms. In addition to sleeplessness, users may experience anxiety, irritability, or excessively high energy. Headaches, lightheadedness, nausea, or gastrointestinal distress might happen in certain situations. Rarely, high dosages might cause mania, paranoia, or hallucinations, particularly in those with underlying mental health issues. Although cognitive performance may initially feel acute, it might eventually become overburdened or disorganized. A person should seek medical assistance right away if they take too much Modvigil 200 and have severe symptoms.
