I currently take both Celexa and Buspar. I have experienced NO negative effects of either of them. I started the buspar when I was still on zoloft before what got switched and I think I noticed positive results from adding the buspar. It was about a month later I started on Celexa, started on 20mg, currently on 40mg, and she might raise it next time to 60mg. I suffer from severe depression so I can't say im good right now but I like it. My anxiety has gotten under control now and its mostly the depression I working on now.
