Hi, I have battled I.B.S. for years and recently my doctor put me on Librax, 2 times a day,taken 1/2 hour before meals. It is really giving me a calming effect which is wonderful. I seem to be having more normal bowel movements, where previously it was either Diarrhea or Constipation, no happy medium. My concern is increased flatulence that I don't seem to feel coming on, so unfortunately it seems to surface at times I could do without it. It has been about 10 days since I started the Librax, is this normal as my system gets used to this drug?
