I never really started dry heaving until after I started taking an antidepressant (Zoloft). I hated the medicine and I didn't think it helped me at all. I haven't been diagnosed with depression necessarily, but I went to a doctor who prescribed the medication so she must have thought something was wrong. I have anxiety and depression. I have passed out once (which I was told was due to dehydration, but I do not think it was. Yes, I do not drink as much water as is, but I had just woken up and was actually having a not so pleasant conversation with my mom) and had a panic when I was driving. What was weird about the panic attack was that I didn't feel the anxiety. I felt like I was on autopilot. I was still driving And was aware of my surroundings, but I was unable to respond. Both of these incidences were brushed aside, but I can't just ignore them. Anyway, back to the point. Ever since I started taking the Zoloft, I've been dry heaving. I would never actually vomit, but I would dry heave and I would get a wave of nausea right before. After I would dry heave a few times, it would be over and I wouldn't feel nauseous anymore. But it would happen several times throughout the day. Someone told me this was normal and not to worry about it, so I didn't. I still didn't like it. I took the Zoloft for about 3 months before I had had enough and stopped taking it. It didn't help my depression or anxiety anyway. However, I still dry heave on occasion and get waves of nausea. I think it may be stress/anxiety induced, but I'm not sure. I would dry heave without even doing anything or just sitting on a couch
