Have had anxiety for couple months now specially when over whelmed by work and kids, and then feeling sad thoughts. I take xanex when needed and unisome to help me sleep due to racing thoughts, this is my second day on citalopram 10mg I was told to take at night so.maybe it would help with sleep, the first night I was ok and also the next day just no appetite and felt a little sob. Today is the second day getting hot flashes nausea, dizziness which then causes me to bring anxious because I'm scared I'm going to pass out. Do I stick with this our stop and try something else?
