Viberzi
"I have been taking this drug for about 2 weeks, and it is a miracle in a bottle as far as I'm concerned.   I've been battling IBS-D for 10  years and never really sought treatment until recently.  Frequent and very urgent BMs for years to varying degrees.  Very sensitive to spicy food.  Always on the lookout for the next restroom... With Viberzi I'm down to time 1-2 per day and solid!  I haven't experienced any side effects as others have mentioned.  My Dr has tried a few other drugs, this is the first that worked for me.  The discount program worked for me.  Worth a try if you have IBS-D."
