Eligibility criteria:

        Inclusion criteria:

          -  Confirmed relapsing-remitting or secondary progressive multiple sclerosis,

          -  Ambulatory for distance of at least 100 meters without gait assistance,

          -  Persistent fatigue for at least 8 weeks that is not attributable to causes other than
             MS, and

          -  Will be able to complete questionnaires and cognitive testing.

        Exclusion criteria:

               -  Untreated depression or screening Center for Epidemiologic Studies Depression
                  (CES-D) scale greater than 28

               -  Significant cognitive impairment (Baseline Short Test of Mental Status score of
                  less than 29/38)

               -  Narcolepsy, uncontrolled sleep apnea, or other primary sleep disorder judged to
                  be likely a major contributor to fatigue

               -  Screening Epsworth Sleepiness Scale score greater than 15

               -  Uncontrolled hypothyroidism or anemia

               -  Other medical illness judged by the investigator to affect the participant's
                  fatigue complaints including current viral, bacterial, mycobacterial, or fungal
                  infection

          2. MS Disease Activity and Treatment:

               -  Clinical exacerbations within 2 weeks prior to screening visit

               -  Corticosteroid use within 4 weeks prior to screening visit

               -  Beta-interferon, glatiramer acetate, immunosuppressant drugs (mitoxantrone,
                  azathioprine, etc.) are permitted if a stable dose has been used for greater than
                  or equal to 4 weeks and there is no temporal association of drug administration
                  with perceived fatigue; elective on-study dose/regimen changes are not permitted

          3. Current or Recent Fatigue Therapy and Other Medications:

               -  Use of more than two doses of ASA (aspirin) greater than 81 mg/d within 2 weeks
                  of screening visit

               -  Use of MS fatigue medications within 2 weeks of screening visit (including
                  amantadine or Central Nervous System stimulants such as modafinil,
                  methylphenidate, and pemoline)

               -  Symptomatic medications (antidepressants, anti-spasticity agents, non-narcotic
                  analgesics) are permitted if a stable dose has been used for >4 weeks prior to
                  screening for antidepressants and >2 weeks prior to screening for other
                  symptomatic therapies and there is no temporal association of drug administration
                  with perceived fatigue; elective on-study dose changes are not permitted.

               -  Current use of acetazolamide, antiplatelet agents or anticoagulants, COX-2
