If you find anything that has lasting effect let me know.
I have had this issue for a few years now. I get to the point my gut is so bloated that it pushes up on my diaphragm and honestly is why I look as fat as I do. When I'm not bloated my gut is at least half. Really sucks when I'm out walking the woods and go up and down hills and need to take deep breaths. I get reflux from stupid things you wouldn't think would cause a problem. Peanut butter, mac and cheese, some fruits will do it as well because of the natural acid.
I use to take omeprazole daily but now I just take it if my reflux gets really bad. Dr. told me to cut out drinking anything with fizz, eat bland foods with no spices including black pepper, and stop smoking. I just say fuck it and eat and drink what I want.
