I was on Celexa (citalopram) for 18 months. It helped a lot with my anxiety and didn't have a negative effect on my libido. I did gain 30 lbs. while I was on it, though. I also felt very lethargic, but everything seems to make me feel lethargic. I lost the weight after I stopped taking it.

I'm on Cipralex/Lexapro now and have been losing weight since I started taking it. I'm still lethargic, but it's not as bad as it was when I was on Celexa.

I hope Celexa works well for you. When I was on it, my doc combined it with a small dose of Wellbutrin to try to minimize the lethargy. It seemed to help a bit. Oddly enough, Wellbutrin did horrid things to me on its own, but it was okay with Celexa.
