I find Betaine HCI and digestive enzymes with meals plus probiotics to be helpful. The gut stays as clean as possible. I actually had surgery recently to reduce turbinate in order for nasal spray to reach proper area, which it couldn’t prior to surgery. Using ipatropium spray and doing much better. Drastic solution but worth the pain since I’m no longer up all night trying to get rid of phlegm running down my throat. I also am gluten sensitive and avoid wheat which causes burning stomach pain. Maybe eliminate gluten.
