I'm not sure who you are asking, @riflemanz64 but if it's me, yes I did have an endoscopy. That was when I was told my Barrett's was in remission. I had been on omeprazole but at my request, I changed and am now on famotidine. I was concerned about some of the potential long-term effects of omeprazole.

The ENT looked down my throat (through my nose) and it was all irritated secondary to post nasal drip. Then I started omeprazole which worked but after approx a year causes the microscopic colitis.

I am now reintroducing foods into my diet, so far so good. I’ve discovered that small amounts of dairy are ok. I will try uncooked greens soon!
