I started Linzess about 5 days ago. On days #2 and #3, I had pretty normal bowel movements. On day #4 I noticed bloating, scale indicated I'd gained 2 lbs. In the middle of the night (3 a.m.), I awoke to fecal incontinence, watery diarrhea in my PJ's, sat on the toilet for about 20 minutes with nothing but watery diarrhea. Has anyone else experienced this? After that episode, I ended up gaining another 2 lbs.
