I was previously on Pristiq and Wellbutrin XR for depression/anxiety. When my doc added Wellbutrin to counteract the sexual side effects of Pristiq, it was life changing for my sex life. I was taken off Pristiq for reasons not related to this post, and this week my doc added Buspar since anxiety is now my main problem. Only two days later I notice decreased libido, some erectile dysfunction, etc. Could this be the Buspar already?
