Is Viberzi correct solution?

Hi,
I have been having bad cramping since a c.diff infection that was treated and I am testing negative now. For years I have had frequent stools due to SIBO and IBS. Still, I am having about seven urgent bowel movements, all formed and long, but mushy. It is not what I consider diarrhea, but it comes out all day long with the urgency and cramping and is unpredictable to a point where I am worried about returning to work. My doctor prescribed Viberzi and I just wanted to ask,

1. Did anyone else take Viberzi for formed stools that had frequency or cramping issues alone? If so, what dosage and timing was best for you?

2. If you didn’t have liquid stool before, Viberzi did not cause that as a side effect, correct?

I appreciate the help! Thank you!
