Hi, my current episode of depression and anxiety has been going on for almost three months now though seems like three years!! I started on St Johns Wort then switched to citralopam and then because I was not eating or sleeping I was switched over to Mirtazipine. I have been on Mirtazipine for 6 weeks now, did feel better for a couple of weeks but have been feeling bad again for the past week. Went back to doctors and he said that I could switch to Prozac but would have to wean myself off current tabs for a week, then obviously prozac would take time to work if they work! Need some advice really, should I switch over or perservere with current medication!!! Can't think straight!! Help!!!!!
