That is quite interesting Snow Leopard. The study states,"In the present study, it was determined that 'the sicca symptoms of SS' are common in CFS patients and were irrelevant to the drugs used. In addition, CFS patients frequently had positive results on the Schirmer, Rose Bengal and gum tests."

It is impressive that the 'sicca symptoms' are listed as additional main clinical features in fibromyalgia. Actually, 36 of our 75 CFS patients (48%) met the classification criteria for fibromyalgia."
