Something I read in one of the many books was that it took months, years for the M to be in the current state and it can take just as long to get it back on track if it does work out.
My rule of thumb is that it takes about as half as long as the "bad relationship" in the eyes of the WAS's time was. Of course, that's far longer than any LBS's wishful time table.
Just as it takes time for flesh wounds to heal, it takes time for emotional wounds to heal.
