I get some kind of reflux everyday. Seeing a specialist in a couple of days. But night times are always worse, I think because by the time I wake up with it, iis already really bad and it causes me to be nauseous. But I find that the nausea is only constant and its almost like its just a side effect from the heartburn and it wont cause me to be sick, although at the same time my brain kicks in and I start wondering things, and then I feel trapped beacase its night time and I feel I cant leave the house and that's when things REALLY start to get worse. So the only reason why its not going away and your getting nauseas is because of your anxiety. (Like me). Nausea does happen with heartburn and reflux some of the time, but its never or extrmeley rare enough to actually make you sick.
