How to tackle bad GERD?

Last year I had a scope and it turned out everything was pretty irritated. I tried switching my medication up multiple times and still do not have a good handle on it. Diet etc helps but only to an extent. I can't handle foods or medicines like I use to do. It's been an awful battle of different symptoms. Nausea, indigestion, bloating, acid reflux, regurgitation and sometimes vomiting. I'm just wondering when this will subside and what if meds don't help anymore? I'm scared that I won't be able to stomach any new medication I might need. It's taking forever to get into the gastroenterologist.
I can't take nsaids or ibprofen anymore and I have chronic inflammation..so it's driving me a little bonkers. Please anyone with similar GERD issues chime in!
