I have read all of these posts. I started taking celexa for panic attacks after a carjacking. I did therapy and believe I am ready to go off the meds. I gained 15 pounds in the last nine months for no reason at all. I thought I was eating more and not exercising - but that was not the case. I have lamented over this fat gain - and am weaning off the Celexa. If you think its causing your weight gain - you are right. Get the therapy and get off the meds.
