Exactly my case!!! But mine was 3.5 years ago. My IBS is mostly C and is what you call Post-Infectious IBS (food poisoning in Guatemala, then Antibiotics , then IBS).
Try Miracle-Mineral-Supplement !!! It has worked wonders on me. I have one month and my stools are very normal now. My pain is nearly gone and I'm not bloated anymore.
Be aware, you'll get diarrhea, and many detox symptoms. Take it easy, go slowly, but take it, take it, take it ... every day. Be patient.
And combine that with a more alkaline diet. I was doing the anti-yeast diet with moderate but inconsistent results, since August this year. Now with Miracle-Mineral-Supplement I feel and see the progress.
I was able to go out to dinner with my company pals, and this is a BIG deal for me. I'm starting to loose fear to food.
But again, it is slow. Miracle-Mineral-Supplement is the ONLY thing from the large list of things I've tried that has actually worked. My energy is up as well as my mood. I'm pretty confident I'll be in remission in a few months.
