I believe that a lot of digestive issues stem from bad diets and bacteria. If I were you, I would start off by taking some probiotics and mastic gum. These should help clear out a lot of bad bacteria. As for a diet, I would look at the paleo diet. Along with these, supplements such as DGL and slipery elm will help with your reflux. I was on PPI's for almost 8 years and no longer take them. I was off all acid reducing medicines and just taking TUMS and had very little heartburn. It has been about
3 months since the last PPI but the heartburn is still there everyday. I think it is a lot better because 2-5 TUMS a day is all I have to take but I have started taking pepsid ac as that prevents heartburn from even showing up, but I think it is better to take that than the PPI's. I also cut off cold turkey. I would suggest gradually reducing your dosage and then migrating to a H2-blocker as others have done. This will make things easier. The hardest part is keeping away from the bad foods as those are the ones you will miss the most.
So basically the plan would be: change diet to help with the primary problems, gradually decrease PPI dossage, migrate to H2-blockers, then slowly ween off of those. Keep in mind though that if your underlying problem has to do with your LES not functioning properly or a hiatal hernia, then it might not be possible without surgery as there is nothing that has been proven to cure those problems.
As far as food ideas, I tend to lightly season chicken/turkey breasts with some season salt or just sea salt and pepper and then eat that with some vegetables such as zuchinni, squash, and mushrooms. I either grill it or pan fry it in cast iron skillets. I usually only eat 1/4 - 1/2 of the chickent breast and fill up on vegetables.
