"I have diagnosed with small bowel bacterial overgrowth.  I had eaten at a restaurant last September and had gotten very sick from the food, and have had stomach problems since then; bloating and constipation.  The GI prescribed me Linzess a few days ago. I took first one yesterday and a few hours later I had such horrible, severe diarrhea.  My stomach cramped most of the day and was pretty nauseated to where all I felt comfortable eating was toast and Cream of Wheat.   Just took my second one, will see if that was a one time effect or if it'll happen again.  If it does, will not take any more as the diarrhea was so so severe that I'd rather put up with the bloating and constipation than the severe diarrhea."
