You probably have IBS....sounds a lot like mine. Not fun. If you Google IBS or on Ask.com one of the first things it will say is food is not your friend. It is true, I was starving myself instead of dealing with constipation, bloating, pain, and terrible trapped gas. It was a choice if I ate I was miserable and would blow up like a pregnant woman, so I would go without eating so I did not have to suffer. I would eat so much plain chicken nooldle soup that I can't hardly look at it any more and I have lost 90 lbs in the last year.
Stay away from any form of caffiene, fatty foods, fried foods, butter and in my case all dairy too plus fruits and vegies also cause me problems. Some people with IBS cannot tollerate fiber, so fiber is not my friend. So I can't eat hardly anything. My IBS is a lot worse then other peoples so it get really depressing. And no alcohol, bad for you. Good luck to you. Leslie
