The Dukan diet has started to do strange things to my head. Namely, that I have started to sniff food. No, really. I can't eat it, but by gads I can sniff it. Take these Cheddars, for example. I inhale, I remember, I try to forget. In all honesty, I caved and ate one. What? I'm only human. It's torture in the workplace, otherwise. Besides, cheese is protein.
