There has to be a point when you may as well pour water on your cornflakes.
As mentioned on the PETA thread, I gave up drinking milk and putting it in cereal or coffee a few years ago. (not for PETA reasons!)
I generally moisten my muesli with fruit squash. Apple works well.
Or I have porridge made with water.
(porridge and muesli often have milk powder in them anyway, so in reality this is just reducing the amount of milk I consume)
I suspect it is like drinking Diet Coke. Your palate just adjusts and eventually you get to the point that real Coke tastes sickly sweet.
