ibromyalgia
"I have been using Duloxetine for  couple months for Fibromyalgia.  I didn&#039;t have any initial side effects.  It has helped me enormously with the muscle pain and spasms. The downside is it has lowered my libido,  I&#039;m fatigued and have weight gain. As I am also menopausal it&#039;s a bit hard to tell what is causing some of the side effects.  The lowering of the libido is definitely a side effect of duloxetine. Not sure if I will continue on this medication."
