Linzess
"So I've been taking this for about a week now.  I have to be near a bathroom within an hour after taking it on an empty stomach.  As soon as I hear the sounds in my stomach, its GI time!  For a person that has suffered with gut problems my whole life, and going more than 7 days without a BM.  I will take it, never a solid bm, always a blowout to be blunt.  To me that's better than going on antibiotics all the time cause of the build up of bacteria in the small intestine and the methane in my stomach reacting to everything I eat and feeling like I'm gonna due cause of the flame feeling in my gut.  Thank God! It is expensive, $30 for 30 pills"
