  • Change From Baseline in Medical Outcomes Study (MOS) Sleep Scale [ Time Frame: Baseline, Week 6/ET ]
  • Number of Subjects With Change From Baseline in MOS Optimal Sleep Scale Scores [ Time Frame: Baseline, Week 6/ET ]
  • Change From Baseline in Work Limitations Questionnaire (WLQ) [ Time Frame: Baseline, Week 6/ET ]
  • Patient's Global Evaluation of Study Medication [ Time Frame: Weeks 1, 3, and 6/ET ]
  • Patient's Satisfaction Questionnaire (With Pain Relief Scale) [ Time Frame: Week 6/ET ]
