I have had the colon noises for 20 years everyday and 24/7 at its worst. Same as you I could deal with the diarrhea but not the colon noises. I am a very shy person and to have the noises goes against my personality and I developed an anxiety disorder because of it. Over the last few months I have had diarrhea on only 2 days out of 3 months and the noises are normal very very minimal. All I can put it down to is probiotics. I have been trying various probiotics over the last few years and think something has worked. All probiotics were taken for 3 weeks at a time. Yakult works. I have also tried activia, Yoplait creamy lite, gastrohealth, faulding probiotics, faulding probiotics ibs support.
