ibromyalgia
"Suffered excruciating lower back pain and was taking Vicodin 2-3 x&#039;s daily for my Fibromyalgia. I&#039;ve been on Pristiq for about 3 weeks. 

Pain has diminished 98-99%. (Sometimes feeling 100% relief. However, miracles I don&#039;t expect.) Only on occasion did I take a Vicodin (and on that day only 1x). This was only due to lower back discomfort I didn&#039;t want to deal with, but not excruciating pain!"
