gas
"For many years, I have not been able to eat out and hardly any restaurant.  In either 15 minutes or up to a few hours depending on where I ate, I would get extremely nauseous and have a diarrhea attack, this after I got extreme swelling in my stomach and belly.  I just discovered by accident that if when I took`Gas-X strips, I either did not get any symptoms or they were mild.  I have been able to add a few good restaurants to places I can eat, (when before it was only at home)  Eating at most fast food restaurants is still a no-no due to MSG and similars.   Taking them 20 min or so before eating produces the best results.  My son found similar results for himself."
