"i am a man and i started viibryd primarily to reduce the sexual side effects of other ssri&#039;s. i have tried many different ssri&#039;s over the years for generalized anxiety and until now zoloft was the best choice for me. i tend to be sensitive to medications and am usually affected by side effects, but at the same time i usually respond well to lower dosages. i personally had severe side effects including vertigo, and watery diarrhea. all the side effects passed after a couple of weeks and increasing the dosage had little effect on me. currently on 20mg and staying there. my libido has improved significantly and i am very happy with the results. side effects were brutal, but worth working through them!"
