Subjects will see the doctor once a week for 6 weeks. During each visit, we will check and treat any side effects. We will ask questions about mood and go through a number of rating scales and assessments that will look at mood and symptoms. Subjects will also fill out questionnaires at each visit to assess their moods and see how the study is going. At the final visit, subjects will have the same physical exam and lab tests done as in the initial visit.
