Hello. I am glad to hear Linzess works or you. Sounds like it actually works too well. I have had IBS-C all my life. I started taking Linzess about 5-6 years ago. It worked great in in the beginning but eventually, my system got used to it and became no longer effective. Medications usually don't work for me so now my doctor prescribes them together with others. Right now I am on Trulance, Motegrity and Linzess all together. They don't always result in a BM, but when they do I am happy.
I hope you feel better and find the right treatment to deal with your IBS-C

Have you tried any natural approaches? Fresh papaya fruit, eaten daily, normalizes the stomach quite well. Also, bone broth powder, put into orange juice, used daily, can be great at normalizing the stomach problems. Try these. They may work for you. Lori Renee
