I've had stomach problems for about 4 year and very bad stomach problems for the last 4 months. I had a camera stuck down my throat and they took a biopsy and everything was OK. I have had really bad bloating for a month and then it went away, well I have just a plain bad stomach. I have big time depression and stress and I have cut my calories to 1600 and I weigh 180 because the more I eat the worst my stomach is and the less I eat the better it is. So I wonder if artificial sweetens could be causing my stomach problems. I'm a 63 year old male. Maybe I should just eat plain old fashion food without all the stuff they put into it. I don't have any allergies.
