Hi, Harry's right. The word "laxative" on Metamucil is misleading. I use it for extra fiber to control diarrhea. It doesn't immediately cause you to go the bathroom - at least the Metamucil wafers don't. I can eat a couple packages during the day, and then not "go" until next a.m. or afternoon. You will notice an increase in gas at first, but it's something your body will get used to.
Let us know how you do with it.
