No I think it's actually helpful to replace "alcohol" with "cheese".. because there is a certain level of socially acceptable alcoholism which goes under the radar unless you insert something else to "test" if it's an addiction, and then you really see the behaviours for what it is
Of course you can be addicted to anything, I would say casually that I'm addicted to chocolate. However I'm actually not, I've never spent the rent money on chocolate, I've never missed half of the kids school plays because I'm "sugar hungover" from the night before. I HAVE sneaked out of a wedding to buy chocolate.. but admittedly we'ld been there since 10.45 and not fed until 8pm!! I don't routinely sneak away from family dos to have chocolate..
