I have suffered with IBS my whole life. As a little girl, about 10 yrs old, I would, like every two weeks, have bouts of severe abdominal cramps, followed by explosive diarrhea and vomiting.....it has reduced in frequency during my adult life. I now have severe constipation, and once a month bouts of the severe abdominal cramps/diarrhea, I rarely vomit any more.

I was dx with IBS when I was 19, and with MS when I was 46......do you think they are related??
