Artvigil 150 mg has some stimulant-like effects, it differs from traditional stimulants like amphetamines or caffeine. Instead of a jittery or strong "rush," most people report a gradual, constant boost in alertness and attention. It encourages alertness without causing intense euphoria. Higher dosages or sensitive people, however, may experience restlessness, a quicker heartbeat, or moderate stimulation that resembles stimulants. When compared to conventional stimulants, it is often regarded as a more gentle and hygienic type of stimulation.
