It is still very little known about how Provigil works. The most important thing, however, that it does. It is thought that Provigil works by affecting dopamine, which reduces the symptoms of fatigue.
The dosages for different types of fatigue are prescribed differently, as this disease can be caused by two different issues – physical and cognitive.
Sometimes, a simply cup of coffee can do the same as Provigil – to help you improve the wakefulness. Provigil brightens the emotions, elevates the mood, improves our alertness and ability to stay focused on a given task…Not something a cup of coffee would do.
