A few months ago I went to see a psychiatrist and was prescribed Zoloft, with no change in my depression after a month. I was changed to lexapro, once again with the lexapro not working they prescribed Cybalta 30mg I think I felt a little better after ring on it over the course of a month. So the next month they upped it to 60 mg I am now almost 3 weeks in and feel very down. It's as if it Plateaued. My question is, is that possible? Has anyone else had this experience?
