Eileen, FIL is Feedback Inhibitor of Lactation, a protein in milk that seems
to inhibit lactation the more of it there is present.  There is a simple
summary of milk production on kellymom that mentions FIL here:

Jean, thank you for your educational responses!  I'm still not seeing a
rationale for having a consistent imbalance in mom's milk such that baby has
lactose overload symptoms, and how this relates to oversupply or overactive
letdown.  The fat is made in there somewhere, and either has to come out (to
baby), accumulate in the breasts, reabsorb or convert to something else in
the breasts, or for some reason not get made in the right proportion in the
first place.
