"i have been on pristiq for 9 months. previously i was on cymbalta to help with depression and fibromyalgia. pristiq seemed to help somewhat at first (for a few months) but then the suicidal thoughts returned. i&#039;m now being taken off pristiq (slowly). it just isn&#039;t working any more and i&#039;m still in deep depression. so thankful that my doctor is switching me to something else.
