I was on Celexa for about 2 years and noticed about 15 pounds of weight gain. I started working out with a trainer in January and changed my eating habits as well. Still can't seem to drop a pound. Talked to my doctor and he put me on Lexapro. I have been on it for almost 2 months now and have even increased my cardio per week and eating even healthier but haven't seen a weight loss yet. Will I ever be able to lose weight while on Lexapro?
