Anyone know what might be causing this?

There have been times where I have to go to the bathroom, and the longer I go, the looser the stool.....not really diahrea, but loose........ I start cramping and it becomes a race of sitting on the john or standing up to throw up in it. I feel SOOOO sick when this happens......I use to get this about every 10 months or so, but I have had many incidences of this in the past two months. I went to a gastroenterologist, and she thought perhaps I had a food allergy, and suggested staying off of milk and dairy products. Trouble is, I do not like milk, and I do NOT eat any dairy products. I do not correlate eating anything in particualr before an attack happens.  
Does anyone know what might be causing be to get so sick??

Have you had a colonoscopy done?If not ask your doc about it.A friend of mine had similiar situation.She now has to stay away from starches in her diet.When starches break down in stomach they form bacteria .

Have you heard or read about IBS (irritable bowel syndrom)?  Your symptoms are similar to what I have read.
