I somehow got in the habit of increasing my PPI dosage over the last couple weeks. My gerd was getting worse so I ended up taking 2 doses of nexium 40mg, and 2 doses prilosec otc 20mg spread throughout a 24 hour period. I took this dosage for a few week, but my gerd kept getting worse. I learned about apple cider vinegar and started taking that, and it has helped. Could taking too many ppis have made my gerd flare up so bad in the first place? Could it aggravate it more? I read something about gerd sometimes being too little acid in the stomach and ppis could make it worse. Anyone know anything about this? thanks.
