Do you experience any food cravings now you've had your fillings replaced?

I've been craving crisps (chips for the northern americans). Does salt help mercury removal? I've also been craving polo mints (i'm not sure if you get them in the US). I'm guessing that's due to the magnesium stearate.

I remember reading a detox book a while back which was saying your body knows when it's had enough of any vitamin, and so you should listen to what your body's telling you.
