"I have struggled with stomach issues my entire life. I started viberzi 3 weeks ago and it has been great. I do have some side effects though. Constipation  and gas lead to some abdominal cramps, but nothing like before. I experience a muscle "soreness/achiness" in the back of my neck and arms about 30 minute after I take each dose, but it only lasts a short while. Nothing that is really bothersome. Viberzi has given me a life I never had. I can leave my house and travel without any nervousness over being sick and I also have been able to be more productive at work. I am so excited to have found something to help me live a normal life."
