Primary Outcome Measures :
  1. To evaluate the efficacy of pregabalin (BID) compared with placebo in assessing the durability of effect for the treatment of pain associated with fibromyalgia among patients who initially respond to open-label pregabalin using Pain Visual Analog Scale

Secondary Outcome Measures :
  1. To evaluate the efficacy of pregabalin (BID) compared with placebo treatment to relieve pain and to improve global assessment, functional status, sleep and fatigue associated with fibromyalgia using questionnaires. To evaluate the longterm safety
