Irritable Bowel Syndrome
"I was recently diagnosed with irritable bowel syndrome and given Belladonna/Phenabarbital, as well as Dexilant (acid reducer).  I felt great for the first week of being on these; however after that it has gone downhill, with severe diarrhea and headaches.  I have lost 13 lbs since taking these medicines and concerned with which medicines cause this.  The Dexilant seems to cause the diarrhea, but I&#039;m left wondering why the headaches are so bad.  Any assistance would be great...cannot function w/the headaches and nothing over the counter touches them."
