Experience with curcumin as PPI alternative?

Hi, all. I am 67 and have recently been diagnosed with Achalasia, metaplasic Barrett's Esophagus, and likely silent GERD. I am trying to avoid long-term use of PPIs and am wondering if others have gotten guidance on use of curcumin or other alternatives. Re curcumin, I'm especially looking g for guidance on dosage, timing of doses, etc. BTW, I have already made diet changes, lost 30 pounds, am using a mattress wedge at night, and have switched to sleeping on my left side. Thanks!
