I have never been able to achieve an orgasm, I was on Effexor (venlafaxine) and now am on cymbalta, they are used to treat my fibromyalgia please help me!

If you were unable. To achieve orgasm prior to use of Cymbalta or Effexor (venlafaxine) - than this goes beyond medication side effect. However, sexual experience can be negatively impacted by depression, fatigue and chronic pain. May wish to explore this issue further with your physician.
