Hello everyone, five days ago I started Sertraline (or Zoloft as it is sometimes referred to). I'm on it for anxiety. I have felt strange on them since, ranging from spaced out/high, to more anxious than usual. My stomach has been off, and I have had heartburn. Tonight I have got nausea. It's a weird sort of nausea, the sort you get antibiotics. Has anyone experienced nausea with anti-depressants and what did you do? I really hope I don't actually v*.
