For Irritable Bowel Syndrome "I have had Irritable Bowel Syndrome-C for most of my adult life, and this medicine is the only thing that calms everything down. I do not take it every day - only when things get intolerable, and even then I usually try to take it at night, as it does cause drowsiness and 'cognitive impairment.' It definitely works, though! In my opinion, it's worth a try."

For Irritable Bowel Syndrome "Great at first until you have to take as therapy for years. I have headaches, confusion, memory loss, mania, loss of sleep. I already have anxiety disorders. This stuff can facilitate glaucoma, Alzheimer's. Blurs vision from the start! Terrible, no integrated health care so docs can learn to see the whole patient and avoid severe disruption of life. I'd rather nurse the severe trouble of advanced diverticular disease, IBS, fructose malabsorption, hiatus hernia type 2, GERD, LPRD. I would rather not be blind and lose what is left of my mind. Terrible medication in the long run. Patients should be educated, better monitored for complications for all medical issues."

For Irritable Bowel Syndrome "Where has this stuff been? I have been suffering with irritable bowel disease since the beginning of June and was prescribed Bentyl. The first few days were four 10 mg pills a day and that sent me into orbit, but the spasms lessened. Then I was to go down to two a day and I managed to be awake here and there. Now I am on a daily dosage of one a day. The side effects are sleepiness and a little cognitive impairment, but the cramping has decreased by 97%. For me, this has been a total blessing. As I feel better I am thinking of switching to taking the one pill at night instead of the morning. But for now, I am changing nothing. I eat a very bland diet, but hey, it is being processed normally."

For Irritable Bowel Syndrome "Meds: Subutex 8mg SL 2x daily (recovering addict), Bentyl 20mg oral as needed up to 4x daily. I have irritable bowel syndrome flare-ups randomly, depending on stress level, caffeine/nicotine/stimulant intake, etc. The first few months, one 20mg Bentyl stopped a flare dead in its tracks. Now it doesn't and I have to double dose, because when I flare, the pain is so severe that I begin vomiting, sweating, shaking, and cannot function at work. The double dose is effective, but causes blurred vision, cognitive impairment, and a general feeling of being 'disconnected' or 'high', minus any kind of euphoria. Going to discuss this with my PCP."

For Irritable Bowel Syndrome "I took 20 mg on the first day and 10 mg the next day, and it was too much. I felt like I was on a drug that was cranking up my nervous system. Bentyl caused me serious side effects: anxiety, pain in the lower abdomen, congestion in my nose like I had allergies, and cognitive impairment in the form of forgetfulness. Never again. This drug is not for me."

For Irritable Bowel Syndrome "This was one of the first IBS-D medicines I have taken. It worked somewhat, but it made me forget everything. And I mean EVERYTHING."
