So I started 5 mg Lexapro 2 weeks ago. I know it takes a while for side effects to get better and to start to feel better, but wouldn't there be some improvement in side effects at 2 weeks in? I feel dizzy and foggy and exhausted and just overall terrible. I have a weird burning in my chest off and on and feel like I'm constantly on the verge of a panic attack. I can't imagine going up any higher at this point. I would think I would feel at least somewhat better. The last time I tried an antidepressant it was Celexa and I felt like that then too. As soon as I went up on the dose I had a horrible panic attack at a restaurant and wound up laying on the bathroom floor so lightheaded I almost passed out! Maybe my body just can't handle these kinds of drugs. I always want to try because I would love to be like others who take them and have such good results, but I'm not sure how long I can feel like this.
