irritable bowel syndrome
"I've had IBS-D for 20 years.  Not a severe case, but persistent and definitely impacted the quality of my life.  I tried everything: low FODMOP diet, gluten free diet, no high fructose corn syrup or sugar, no caffeine, immodium, bentyl, wellchol, rifaxin, peppermint pills etc. - nothing worked.  Multiple colonoscopies found nothing wrong. I finally tried 75 mg Viberzi and it worked immediately.  No side effects whatsoever so far.  Only two issues: (a) trying to remember how to be normal and (b) so far my insurance refuses to pay for it.  Got a 90 day supply for $30 on a special promotion but after that if insurance does not cover I don't know if I can afford to stay on it.  Cost per month is around $1000 - $1200."
