When I was pregnant I became semi-obsessed with citrus. It wasn't a craving. I didn't need citrus, but when I ate something that could be lemon or orange flavored, I chose that.
This brings me to one of the things that I did want but couldn't have during pregnancy. No, I'm not going to speak today of really awesome french fries with garlic aoili. Goodness, how I wanted those... 
I'm talking about limoncello. Cold. Right out of the freezer. Little shot glass of it after dinner...
I haven't been without it since the little bugger popped out.
