Hi, I am 21 years old and had recently been to the doctors and found I have IBS. He put me on a high fiber diet and it has been a couple weeks and I really don't feel that big of a difference in the way of how I am feeling. The biggest problem that I have and concerned about is that when I am in school sitting in class for two hours straight, I get gas pains and spasms. It is very uncomfortable and annoying because my stomach then starts to get noisy as well. I am always usually nervous at school especially whith test taking, but it is getting hard for me to concentrate in school. I am kind of new to all this. What should I do to help with that? Any suggestions?
