BTW when I was DXed "silent" GERD two months before DS I was rabidly compliant: I bought a bed wedge, stopped eating after 8pm, gave up coffee, tea, all caffeine, carbonated beverages, highly acidic foods -- uh, was a little less compliant regarding chocolate (an esophageal sphincter dilator) at the time but don't eat it now. And of course I lost about 110# after the DS. In short I did EVERYTHING they recommended for "lifestyle changes" and went from no discomfort from my "silent" variety of GERD to ruin-my-day heartburn just from trying to QUIT the PPIs!!
There are articles, scientific data, news reports galore on dangers of PPIs and the impossibility for many to get off them because of the well-documented rebound effect.
Oh and my atty husband has said the lawsuits against the PPI manufacturers are in full swing, for the serious health side effects, the dependence and even the kidney stones.
It is supposedly easier to get off H2s. The trouble for me was the H2s weren't resolving the problem -- the problem that I wasn't even aware I had until I tried to get off PPIs. My PCP prescribed Sucralfate (which supposedly coats the esophagus and stomach) to take while trying to get off the PPIs. So I was taking the 2 H2s, the Sucralfate and like 10 Tums and was still miserable. (And ended up in surgery from the Tums induced kidney stone.) I mention all this as maybe the Sucralfate (prescription) will help you?
