If anything, it’s the reintroduction of grains that I would suspect is your problem.
I cannot eat plants at all but grains are particularly bad. Terrible gas pain and bloating happens. That happens even if I eat green veggies but it’s markedly worse with grains.
I once had one of those sparkling alcohol drinks in the cans that has no carbs and was super sick the next day. Turns out it was a grain based beverage as opposed to the Truly type which is sparkling water and not grain based.
Grains are terrible for the gut.
I would first and foremost eliminate all grains in food or liquid form and see what happens.
I personally feel wary about meds that affect digestion. I wonder if you truly do need to reduce acid, and many times that is a misdiagnosis, if sodium bicarbonate would be helpful or using some digestive enzymes?
I would be worried what a troubled gut would do to the long term ability to keep your weight off. I would definitely implement no grains immediately if I were you.
Meat is tremendously easily digested and most completely digested as well. Provides the most nutrients. I would not suspect meat in any way.
Lots of people go carnivore where they eat beef and drink only water as an elimination diet to discover what foods are troubling them. It’s considered the ultimate elimination diet because it’s so gentle on the digestive system.
Once they go a few weeks or a month, they slowly reintroduce things in small amounts and can easily discover what causes them issues.
That may be something to consider as well. If you don’t want to go that far, I would definitely cut out grains 100% and at least consider reducing most other plant foods that aren’t leafy greens.
The only other thing I can think to suggest would be really working on introducing good gut bugs. Eating refrigerated fermented foods with live bacteria or getting a good quality probiotic may help. It didn’t help me though I can tell you. I tried that route before going carnivore.
I hope you resolve the issue soon though. I know how bad that feels. That’s exactly why I eat carnivore.

Most of the remaining ulcers are associated with the widespread use of pain relievers known as nonsteroidal anti-inflammatory drugs, or NSAIDs.1 Cells in the stomach lining require chemicals known as prostaglandins to produce a thick coating of gelatinous mucus. This mucosal lining acts as a natural defense by keeping acid contained in digestive juices from burning the stomach wall and by preventing harmful bacteria from entering the bloodstream or lymphatic system. NSAIDs block the production of prostaglandins, thus relieving pain and inflammation but also leaving the stomach lining susceptible to ulceration and invasion by H. pylori.
....Approved in Japan as a drug to treat ulcers, a novel zinc-carnosine compound has been found to strengthen the mucosal barrier, coat the stomach, and inhibit both the growth and damaging effects of H. pylori. These benefits of zinc-carnosine are enhanced by cranberry and licorice, two natural agents that also support gastric health.
...Zinc-carnosine has also been shown to enhance healing of the stomach epithelial lining, by inhibiting production of pro-inflammatory interleukin-8 and by preventing inflammatory white blood cells from adhering to epithelial cells.14,15 Additionally, scientists have noted that zinc-carnosine decreases the activation of nuclear factor-kappa beta (NFkB), a powerful inflammatory mediator that scientists believe plays a role in numerous chronic disease states such as cancer and arthritis.14 Scientists believe that strategies to reduce the activity of NFkB may benefit the entire body by helping to avert such diverse conditions as cancer, diabetes, and heart disease.

Here's a site with some ideas about healing the mucosal membranes with slippery elm - maybe worth a try. Plus some other info about B12, gut bacteria, and Autoimmune Metaplastic Atrophic Gastritis. https://www.juliedaniluk.com/health-tips/gastritis-the-inflamed-stomach.html

Just by way of an update. H.Pylori was ruled out by tests.

I do eat a lot of meat, eggs, cheese, nuts, seeds. Those would form the main part of my diet. When I say I eat some grains, it is very limited. I might eat one small tortilla shell every couple of weeks. Once in awhile i will have a small piece of very good quality, stone ground (heritage grains including all the germ, etc) bread toasted with peanut butter...maybe once a month.

I really don't think it is grains. I've had occasions when I've eaten more grains than described above (while on holiday) with no reaction.

My Doctor is fixated on Alcohol as the culprit. Which until recently I 100% agreed with, but then I had an attack but had not had very much alcohol at all as I was still recovering from the last bout.

I do not want to stay on the Pronton Pump Inhibitors for ever. The long term side effects can be serious so both me and the Doctor would like to eventually phase them out. Right now however my stomach lining needs to repair itself and reducing stomach acid is the recommended way to go.

Thanks everyone for taking the time to reply. You are all too kind for words!

But you still had some alcohol?
I don’t think you can say it isn’t alcohol if you still had some. Less doesn’t equal none.
It may be the type you’re having also.
