Along with dinner mints I cut way back on caffeine I mix 1/2 caffeinated coffee to 1/2 de-caf and its actually really good coffee. That also helped me with my sleep, blood pressure and anxiety. I'm also a hot food fan, the hotter the better from cayenne pepper to habanero's etc. I have not given up those at all. Also I have a tiny hiatal hernia in my right chest side (found during a chest MRI). Now I keep a food journal and so far so good! But the big thing was giving up red meats and how it was causing inflammation and giving me a whole new set of symptoms I did not have the when I had Alpha Gal years ago. I really do think as any part of a GI or ENT workup that an AG blood test should be done. If it comes back positive see an allergist and go from there. Here is a link with some patient stories.
