"I am 53 years old.  I have had serious problems with the constipation due to irritable bowel syndrome, for years.  I was only able to take Zelnorm for two months before it was removed from the market, but they were the best two months of my later adult years.  No pain, easy bowel movements, loss of doughy feeling in my abdomen, less tired, and more symptoms were gone with Zelnorm.  If you can't bring it back, please find an alternative that works as well.  PLEASE!"
