I don't know if you have IBS but it fits the symptoms, in my opinion. When it comes down to treating your stomach bloating and cramping it is all about DIET. You may think you are eating well, and maybe you are, but cettain foods cause cramping and bloating easily.
Foods to usually avoid!
Coffee, alcohol, sugar, fats (must cut out)
High fat foods ie chips, peanut butter, baking, cheese, egg yolks etc.
Sugar processed foods ie. chocolate, candy, juice, pop etc.
Processed foods ie. canned, packaged, micromave prepared foods etc.
Raw vegetables and fruits (try dried fruits or cooked vegetables)
Whole grains (stick with sourdough or french bread)
Every person is different so cut all the common bad foods for IBS then slowly add one food in at a time to figure out what bothers you and what doesn't.
