I've read a lot about what causes IBS. What comes to mind for me is the fact that I had a terrible reaction a day after eating a few WOW chips. I was very sick with D and terrible cramping and pain for a week. I ended up going to my docter twice and found out that the Olean used in the WOW chips caused intestinal bleeding. It took a long time for me to feel "normal" again. I wonder if that caused my IBS problems. Anyone else experience something similar??
