irritable bowel syndrome
"I took Linzess earlier this year when I was constipated constantly from IBS and gastroparesis. It either gave me diarrhea or didn't work. Then my bowels normalized for a while so I quit taking it.
About two weeks ago, the constipation started again, so I began taking it again. This time it was wonderful. I haven't had diarrhea; instead, it gives me a regular bowel movement each day and I don't have to stay at my house for several hours after I take it to make sure I stay near a bathroom. I'm on the higher dose of it. This is the way I had hoped it would work from the beginning."
