irritable bowel syndrome
"I have an ibs problem 2 or 3 times a week about 30 minutes after eating. I have severe cramps with diarrhea. The pain is so bad that I experience gagging and dry heaves or vomiting. Sometimes I have constipation.  When I feel the first cramp, I take a librax and the cramps stop like a miracle. I keep my librax with me at all times because I never know when I am going to have an attack."
