Approximately 100 male and female outpatients, who are between the ages of 18 and 65, will be enrolled at four sites in the United States. This study consists of two parts. The first part consists of 6 weeks of open label treatment with a selected SSRI \& double blind treatment with Provigil or placebo (inactive medication).
After the six week double blind treatment phase all patients will enter a four week open label treatment phase with Provigil. The dose of Provigil is not to exceed 400 mg and cannot be less than 100 mg per day. They will continue taking the prescribed SSRI.
