Sorry if this has been done! I have NO food cravings at all (am 30wks) but have quite an overwhelming addiction to the smell of green Radox. I had it when pregnant with DD2 too and used to put it in the oil burner!
Also: the smell of Pine Flash
Shield soap (found a bar in the back of my kitchen cupboard, it smells like PROPER SOAP!)
the Fairy liquid my boss has at work- it's a foreign bottle from the pound shop and smells different to regular Fairy and I wash my hands in it rather than the hand soap
(super dry hands alert!)
When my friend was pregnant some years ago she used to carry a jam jar of white spirit in her handbag to sniff. Another friend used to stand with her head right inside one of her kitchen cupboards because the smell at the back of it was addictive.
It's not just us, surely? :o
