I know it's been a topic here before, but starting a new thread since it's 2017. What are some of the most common complaints on Lexapro, I know most side effects subside after two weeks. I'm very afraid of starting and gaining weight, not sleeping, being too tired to exercise or even more anxious. I would classify myself as mildly anxious, somewhat depressive tendencies, I'm afraid to start taking anything though. Any advice?
