I am trying to do that, second time. Last August I took 2.5 weeks lowering the dose, skipping days. I think I rushed the process. Ended up with IBS symptoms, which eventually tamed with the FODMAP elimination diet. But still had GI problems, and worsening chest pains, so perhaps I got rebound GERD. Scoped a second time in February, dilated, put back on a different PPI. Took full dose for two weeks and am now trying to wean off them more slowly than the first time in conjunction with using Gaviscon Advance, alkaline water, melatonin, and Dr. Aviv's no acid diet. Some people swear by Dr. Koufman's advice, you can google her blogs (and a Reddit user detailed her answers to his $500 consult so others didn't have to pay out). Still having problems, e.g., I was doing a plank, which I have done for several months without incident, and suffered a reflux attack. Am going to add chewing sugarless gum to stimulate saliva, and again cut back on amount of food I eat per meal. I am a member of the acid watchers warrior group on Facebook, and people there say it takes at least 3 months to heal. Good luck on your journey. Don't be impatient. I would be interested in hearing success stories from others.
