Well I switched back to zoloft and am having chills, feels like tremors and nauseated . I went to the er and they said I have an ulcer as well. The zoloft is making my anxiety and nausea 6 times worse i put in a call to nurse on Friday and she didn't call back . I haven't taken my zoloft today and my anxiety is somewhat better . I was taking 50 mg but went back to 25 mg after talking to the dr . I'm basically in hell. This is far worse then my depression and anxiety
