I am a new memeber although I was diagnosed with IBS eight years ago. My symptoms are usually very mild, but the last 3 months have been difficult. I don't suffer from diarrhea, per se, but I have anywhere from four to 10 movements in about a 2 hour span nearly every day. It is very exhausting and upsetting (which makes things worse). My GI put me on a high fiber diet a month ago and I'm still having problems. He recommended yesterday that I start taking Citrucel three times a day. Does anyone else have this many movements and did Citrucel work? My GP also put me on Levsin, but that doesn't seem to help much. I'm going on vacation tomorrow, so I'll be sure to pack plenty of Immodium (an IBS-D suffer's best friend).
