I give myself the water rule as well, if I am really craving something I make myself drink a large glass of water first, that way I don't indulge as much. I find it works really well with soft drinks etc. And other stuff I try to convinve myself that I don't need it, but there does come a point when I have to have it....... so I try to find ways to limit it, ie if it is Cobbs Slightly Salty Slight Sweet Popcorn, I pour a portion into a small bowl and put the packet away and only allow myself to eat what is in the bowl, otherwise if I sit with the packet I can easily devour the whole packet *redface*
