depression
"I tried Prozac, Paxil, Cymbalta and Lexapro before I was put on Pristiq. The Lexapro helped but left me a sexual zombie. So my psychiatrist started me on 50 mg of Pristiq. Within days the sexual interest and feelings returned. After two weeks, she upped it to 100 mg and I've not had to take any anxiety medicines. 
Negatives: Nausea, upset stomach. Very vivid and sometimes very frightening dreams. A lot of tossing and turning. Fortunately, I have a very patient and loving partner who has been with me through all these months of depression. I will say that the medicine has made me much more positive and outgoing, and it is amazing how other people respond."
