Eluxadoline
"After having my gallbladder removed 2 years ago I have been battling IBS-D.  I have been on Welchol for about 2 years and it's ok, not great but ok. I was taking 1 a day but I think it needs to be upped to 2. My doctor gave me Viberzi to try, I put it off for a while then finally took it. Days 1-2 were great. Days 3- 4 went down hill fast. by day 5 I was staying within 5 feet of the bathroom. I didn't realize one of the side effects was dizziness (since I have vertigo I figured my allergies were acting up), weakness & major gas. I had to stop taking it so I could actually go to work. I think I'll buy stock in Immodium. I am very disappointed this didn't work, so many people worse off then I am did well on it. It's so frustrating."
