See here's the thing. I don't exactly crave anything at the moment. Which is really helpful in the run up to my birthday (or not. I'm hard enough to buy presents for as it is!) but not useful in terms of obeying-the-meme. Even my desire for an iPad or iPhone 4 is just a mild niggling.
I do, however, get a lot of food cravings (despite my decidedly empty womb) and I can eat the same food over and over again until either Craig or I get sick of it ... it's usually Craig.
At the moment I crave:
Breakfast - Greek yoghurt, rolled oats, & honey.
Lunch - an apple and a handful of pretzels.
Dinner - Mexican food. Or rather, chipotle sauce.
My most recent non-comestible craving (my new baby camera) has been sated.
