I have been having diarrhea and pain, etc. for 6 months and have had many tests, the last of which was a colonoscopy done today. So my GI has diagnosed IBS and put me on Bentyl 2x/day. I'm looking forward to getting this under control (hopefully) but I'm a little confused as to what type of fiber I should be eating. I've been reading to increase fiber but that some types may worsen diarrhea. Help!
