Low Dose Naltrexone (LDN) has been reported anecdotally to reduce the symptoms of Fibromyalgia, a Chronic Multisystem Illness. The drug may work by regulating natural pain-reducing systems. In this study, we will administer both LDN and placebo to a small group of individuals with Fibromyalgia and Gulf War Syndrome, both Chronic Multisymptom Illnesses, to assess the drug's efficacy in treating the condition.
