I had a good result with a 1-step in 2002. I don't recall the exact frequency, but I was in fine shape to fly home after three or four weeks, and return to (desk) work in six weeks. I did use Lomotil quite regularly in the beginning, as well as Metamucil, and I had good success with trying to "hold it in" for longer and longer intervals to "stretch the pouch." How old is your son? That can affect what approaches are practical.
