Primary Outcome Measures :
  1. Fatigue [ Time Frame: 42 days ]

    A vitality subscale of the generic health-related quality of life instrument, RAND-36, will be employed to assess fatigue.

    A Visual Analogue Scale for Fatigue (VAS-F) will be concurrently administered to assess fatigue and compare to the RAND-36 fatigue assessment.

Secondary Outcome Measures :
  1. Health-related quality of life [ Time Frame: 42 days ]

    Adaptive Capacity Index - 21 item questionnaire to measure a subject's ability to adapt to stressors

  4. Adverse Event Monitoring [ Time Frame: 42 days ]
    number of patients with any untoward medical occurance as a measure of safety
