Hello, I will discuss your health-related issues with you to help you make a decision. Armodafinil reduces sleepiness caused by narcolepsy and other sleep disorders, including periods of stopped breathing during sleep. Taking Artvigil 150 mg every morning, approximately 1 hour before work begins, is the recommended dosage of Armodafinil tablets for patients with sleep disorders. This medication should not be used to treat sleepiness that is not being diagnosed as a sleep disorder. It does not replace the need for adequate sleep.
