I also have a history of erosive esophagitis. I currently have it as well. I had been taking aciphex for the last 5 years, and got erosive esophagitis anyway--I guess just from breakthrough acid. My GI doctor switched me to zegerid. I started it last week, and I'm still feeling the same symptoms in stomach and esophagus that I was experiencing with aciphex. But I'll give it more time. There are a number of different PPIs, and they are pretty much the same (per my GI), but what works for one person may not work for another. I'm sure there are natural things you can take, and I'm sure someone will come along and help you out. I would tend to believe your GI, though, in that a PPI is the best way to heal the erosion. You probably wouldn't have to take it forever. I think, on average, 8 weeks is the typical healing period for erosions/ulcers.
If you can supplement with something OTC (i.e., herb of some kind), that may do the trick.
