Modafinil overuse can cause discomfort and overstimulation. Anxiety, restlessness, a fast heartbeat, headaches, nausea, lightheadedness, or sleeplessness are possible symptoms. Excessive dosages may also result in anxiety, irritation, or a jittery, "wired" feeling that makes it difficult to focus or unwind. Confusion or high blood pressure are possible outcomes. Because Modvigil 200 has a high dosage, using more than is advised raises the danger. To guarantee safety and avoid problems, medical treatment is crucial if serious symptoms arise.
