Thankfully I am blessed with a Cast Iron stomach.
I can get up in the morning, drink 2-4 cups coffee, then top that off with 2 Extra Strength Bayer aspirin, then drink a cup of coffee an hour all day, along with 2 Aspirin every 2-3 hrs.
I have yet to encounter any food that bothers me in any manner.
Just last night, I had 3 Chili Dogs topped with onions and Cheddar, along with Nacho Cheese Doritos & a Coke.
Wife just put a dab of chili and a light sprinkle of Cheddar on hers and was frightened that it would wake her with heartburn in the middle of the night.
If my stomach ever bothers me, then it is serious enough to see a Doctor.
