I have been on Celexa for about 2.5 months. 20mg, then more recently 30mg. For the first month I had an aversion to food, but that is getting better and my appetite has come back a little. I have lost about 10lbs on this medication and I am not able to gain it back. I've always been thin so I'm not sure if it's genetics in part, the medicine, or maybe I am not stress eating anymore. I also think my stomach has gotten used to less food. Has anyone else experienced weight loss on their AD? How did you handle it? I am afraid to switch medications because this one is working well on my chronic symptoms.
