Massive food cravings

So lately, I felt a lot like a pregnant woman. Not because I am thinking about baby names (well, for my sims) or looking at cute baby clothes in the mall or crying over everything (well, sometimes) or because I'm actually carrying such a little parasite in me.

No. I'm just having those massive and weird food cravings pregnant woman get.
Especially tomatoes and silver onions in vinegar. I eat them raw like apples and can easily get down 2 kilos in an hour.

What to you think... does that harm in any way? Can I give in to that craving and just indulge? :)
