i started out taking Celexa for a few years for anxiety. it helped but i always felt like I wasn't 100 percent on it. I am now on 10 mg of Lexapro and I started at 5mg. I felt good at like week 5 or at least a lot better but since I have been on 10mg I thought it was even better but that last week or so has been miserable. two questions. is the drug causing the shaky hands and will it go away? Also should I go up to 20mg
