Generally most people will tell you to stay away from spicy foods, as they can upset your stomach, and cause all kinds of havoc, but the truth is that every is different.
What you should do is if you really want some chili sauce, have just a tiny bit, see what it does to you, then go from there. See if it bothers you, if not you're good to go, if it does bother your stomach, well, you should know then what you won't be eating for a while
