For Irritable Bowel Syndrome "I've been on Bentyl for 3 1/2 years, and my IBS is so much better when I take my pill. Initially, I had severe dry mouth that lasted for about 3 months, but I no longer have that side effect. I take a pill one hour before I eat, and I can pretty much eat without worrying about a flare-up. If I eat a meal or snack with little or no fiber, my stomach gurgles and I get gas, but no diarrhea."

For Irritable Bowel Syndrome "I had had early morning diarrhea (no pain or discomfort) for about six months. MD recommended colonoscopy, which produced a diagnosis of microcolitis. I had already treated this with daily Imodium and was doing okay. After the colonoscopy, I had horrible gas pains whenever I engaged in aerobic exercise, and sometimes just eating would instigate them. I was given Pepto-Bismol 4X a day-stopped diarrhea, but not gas pains. Only a heat pad or hot bath would do that. Then I was given dicyclomine, and after a week, the pain subsided. I still feel a knot of gas in LLQ, but it no longer hurts!"

For Irritable Bowel Syndrome "I found out in April that my rheumatoid factor was 48, and that set the ball in motion. I have other disorders, most likely, they are all autoimmune diseases. I used to weigh almost 300 pounds, but I worked hard after my back surgery, and I got to a happy 160 lb. Now, whatever is going on with my bowels causes constant diarrhea, tons of gas, and severe abdominal pain. I just started Bentyl yesterday, and my diarrhea is 100 times worse, why, and will this go away as my body adjusts?"
