Provigil has emerged as the main ingredient of many success stories and the best part of this drug is the fact that it has a success story of its own as well. If figures can tell you something about this success story then we can put it like this, in the last couple of years, they have registered an increase of 70 percent in the sales of Provigil. This is quite a number when we compare it with the fact that most of the medical practitioners are still experimenting with it and people suffering from sleep apnea and Narcolepsy are less or negligible if we can put it like this. Now who do you think is purchasing Provigil, which is this new segment of a market that wants to experiment with this drug? The answer is simple; Provigil has defined a new role for itself. Provigil has defined a new target audience for itself and here we are talking about people who are suffering from daytime drowsiness or excessive sleepiness during the day.
