Artvigil 150 mg works to improve your wakefulness by stimulating the brain and causing a release of dopamine, which is an important neurotransmitter in the brain that’s linked to our reward systems. This explains why we become pumped up and eager when we're joyful or just about to do something amazing. Waklert will assist you in staying alert and focused on your objectives during the day, but it cannot take the place of a restful night's sleep.
