constipation, chronic
"62 year old male, diagnosed with IBS-C at age 57.  The product literature for Linzess says it is not a laxative, but with me it operates just like a laxative.  I take it on an empty stomach, it works in 3 hours, it causes the same sort of watery stool as mag cit, but it is finished after 3 trips rather than 20, and my doctor says Mag cit will cause kidney damage, Linzess won't.   I took Amitiza intermittently for 5 years, 16 mcg at a time, usually with similar results.  This notion that Linzess causes less cramping during buildup or that it calms the colon seems like marketing jive.  I wish it came as a tablet that could be cut, I think the standard dose is too strong for me."
