Oooh just remembered I craved tangerines during my first pregnancy, would eat a bag full in a couple of days!!! Also with the 1st I desperately wanted Whippy or McDonalds Ice cream, but I didn't have any as I'd read somewhere it wasn't that safe during pregnancy (unfortunately!). I also remembered working in an icecream kiosk and remembered how unsanitary those ice cream machines can be if not properly cleaned and sterilised!
Still waiting for a serious craving with this pregnancy.... apart from the ice cubes of course.... sitting here crunching ice as I type! lol
