irritable bowel syndrome
"I've been on Viberzi for a little over a month now and it's been fantastic.   My only problem is, each morning when I take it, i always feel like my arms way 100 pounds so, I lay down for a little while until that passes but then I'm good to go for the rest of the day. I'll take a little discomfort in my muscles for a day of not having to worry about pooping my pants"
