 TITRATIONMAINTANENCE PHASE: If you continue to qualify for the study after the Visit 1 tests have been reviewed by the study doctor or his staff and you have completed the washout phase, you will return to your study doctors office for Visit 2. The length of time between Visit 1 and Visit 2 will depend on the kind of medications you are taking and may need to stop before entering this study. At Visit 2, you will have your blood pressure, pulse and weight measured. You will be asked to answer questions for the same two scales that you completed at Visit 1. You are asked to return all medication bottles even if empty, partially used or unused to each study visit. It is very important for us to be able to check study drug compliance.
