I have been hearing about people success on this site with different kinds of nonprescription drugs/supplements, as well as the best fibers to take. I am over my long list of different revolving noneffective prescription meds that i have been trying for 10 years. Plus in the last year my ibs-c and ibs-d has gotten worse with even more severe cramps/pain. What has worked for you all? I could use some direction with so many different things out there. What has been the most effective for you all?
