Celexa was fine, for me, when I first went on it. I did gain weight during my time on it, but not at first. I attribute to my unawareness of a certain food items total dietary content. Of course had one doctor explain that something does occur with carbs and ssris feed into that. It's then harder to lose weight while on. I lost weight after coming off it. My second experience, I didn't stay very long, side effects were both aggravating on one effect and scary on another.

Here's some articles I found on both. Hope it helps.
