Even with a partially wrecked Nissen, partially reherniated too, I only need Nexium for a week or so once in a while. I didn't believe my gastro that Nexium would stop nausea, but it does.
Nexium doesn't however, stop chest pain when I eat, because part of the stomach is above the diaphragm again.
It is worthwhile to see the doc and get a barium swallow to see what is going on. Finding out why there is reflux or pain or whatever symptoms goes a long way toward staving off panic and worry.
