My father has this same problem with milk.  There are a few thing you can
try before going back to the doctor.

1.  Cut down on milk and milk product intake.
2.  Try the Lactaid milk or Lactaid pills (before milk or milk products)
3.  Try Soy milk.  (I drank this until I was about 7 or 8)

I hope that these ideas help.
