F.R.E.
I think that more research on flatulence is needed. I have had the problem, on and off, for decades. Sometimes I go for years without it, then it starts again. About 2 weeks it started again which I vomited and had diarrhea after eating out. My theory is that something one eats can change the mix of intestional bacteria and, depending on the bacteria mix, the problem can come and go. If I am right, consuming the proper culture of friendly bacteria should solve the problem. However, I have never seen anyone else postulate this theory or propose the solution.
