I've been on Celexa for 4 years. I started at 5 or 10mg and now take 40mg. I never had problems with weight gain on it. I was on it with Trileptal and stayed fairly stable for a few years. I hope you find something else that works for you. I know for me, I have to switch about every 6 months. It's awful. But everyone is different and I am sure you will find something that gets helps the mood swings.
