How many hours does Waklert 150 last?

[ameliamartin]

Waklert 150 (Armodafinil) usually lasts 12 to 15 hours, depending 
on the patient's metabolism, body weight, and overall health. Its 
lengthy half-life makes it suitable for patients who suffer from 
narcolepsy, shift work sleep disorder, or obstructive sleep 
apnea, allowing them to remain alert and concentrated throughout 
the day. The effects typically begin within 1 to 2 hours of 
taking the pill and gradually fade without a sudden crash. 
Because of its length, it is best taken in the morning to avoid 
disrupting overnight sleep.
