I am sorry you are feeling so bad believe me, I know how you feel! There are no real remedies for me. I just dealt with it b/c of my m/s I couldn't even take Tums or Pepsid over the counter. The dx can prescribe Zantac and Pepsid but it depends on your dx. It works for some people and doesn't for others. No, carbonated drinks,sour candy,apple citrus fruits,greasy foods,chili,beans,tomato sauce, and some others that I can't think of.
How far along are you? I still have indigestion real bad like when I burp sour food comes right back up(sorry). I imagine it will only get better when I am not prego anymore.
Hope you feel better,
