I think its the preserves in food to make it last longer that causes IBS I started in my 20s having problems was 50 this year only last few years i realized what the the problem is! Doctors weren't much help. Good old google!

Preservatives and DYES! Yes. Also, make sure with ibs-d to eat more soluble fiber, never eat insoluble fiber foods alone. I also take citrucil, cultures and florastor.

Didn't work for me and I even took the highest dose. Sometimes I would take Miralax along with stool softners and then I would take the lizness. I get spasms in the upper left colon. I've tried pepermint and aloe, but that doesn't help. It's amazing how many suffer from IBS.

It works for me.

I swear by Meberverine
