irritable bowel syndrome
"I have ibs w/ constipation. been taking the 145 mg for about 3-4 months. The first two weeks I was on linzess, it didn't help me at all. So my doctor told me to take double dose.(found out i had a blockage, which the double dose with miralax on top got rid of) I got diarrhea for about a week, then went to have 1 regular bowel movement almost every morning after the pill. I was feeling better than ever. It did give me headaches, and distension though for about a week. After about 2 weeks on double dose, I went back down to a single dose. Everything was still going smoothly. Until about 2 weeks ago I've been getting urgent diarrhea everyday for about 6 hours after taking the pill. And ocassionally getting stomach pain and nausea again (which is why I started)"
