Hi, I am new and am not sure if this will help you... but I am on lexapro as well and have gained weight. I am wondering if the weight gain might be more due to the fact that your symptoms are better not really a side effect of the drug. I think my weight gain may be due to the fact that I am less active and before the medication my body was working way too hard. With that said... if you find something that works better for you.... please let me know. I am not enjoying my new chub!
