I've had IBS-D for 2 1/2 years, up to 8 or 10 times a day. My doctor recommended basic, over the counter store brand Fiber Laxative. I didn't believe him, could a laxative actually help??!! Well, I bought basic "Equate (WalMart) Fiber Laxative", cut each tablet in half and started taking it last week. One every morning. I noticed that my "episodes" went from 10 a day to 4 right away!! And this morning, I actually had my first "normal" BM in over a year!!! My waist is not so swollen, I've lost 7lbs, and I was able to "pass gas" last night too!! I'm amazed. So, if anyone wants to try this and let me know how it works for you! I'll keep you posted on my progress.
