I started taking 50mg of zoloft 8 days ago. The first 2 days were fine, just a little spacy feeling but then on day 3, I started feeling anxiety and kind of a speedy feeling. It got worse on day 4 and 5 then it has slowly declined but I still feel very anxious. I am toughing it out at work but finding it hard to concentrate. I take it at night and I take sleep meds to go to sleep so I sleep good but when I wake up I feel anxious. I keep thinking it will go away soon but it keeps hanging on. Has anyone experienced this and if so what was your experience?
