I had a craving of lemon softdrink (like solo), that started before 12wks... But then all my other cravings, short lived as they were, were all thanks to the power of suggestion. I had a craving for tinned spaghetti and that only lasted a few days. I had a craving for liquorice coz I watched MASH where Klinger was trying to eat a Jeep. He ate a windscreen wiper and hey presto! I wanted liquorice.
