The taste that really satisfies

I've been disappointed by my lack of pregnancy cravings. As any female over the age of 10 could tell you a proper craving makes whatever it is you 'must-have-now-or-I'll-die' so much better when you finally get to have it. So in my mind, if a 'normal' PMS-y craving for chocolate makes a Tim Tam better by 3X then a pregnancy craving could make it better by, I don't know, 15X? That would make it better than just about ANYTHING else on the PLANET. A Tim Tam that was 15X better then any other Tim Tam you've ever had? Surely, this is the reason why people keep having babies.
So I've been a bit miffed that I've missed out on that aspect of pregnancy so far. However, I have been reading about other people's cravings (bless the internet) and there are cravings out there for things I didn't even think it was possible to crave. Forget the boring ones about dirt and metal shavings - these ones are a bit frightening. (I promise I have not made any of them up.)

I dont know what it is but I crave vicks vapor rub. I put it all over me before I go to sleep and just recently I rubbed it on my gums to taste it! I love it! is that weird? I also love the smell of Pine soil. I mop 3 times a day.

I'm 38 weeks pregnant with my second daughter. Throughout both pregnancies I've craved bubble bath - I've never drank it out the bottle but I have eaten the bubbles it creates in the bath every now and again!

I have had the strangest cravings for rubber and also tile adheshive, just anything that you really should not eat!!!

Since I saw someone washing their car I cannot stop thinking about chewing on a sponge, had to go and buy one today to chew on. Im not eating it, just chewing on it.

Toilet paper...talk about strange! (...) my body may be lacking something it needs...but what could toilet paper have that I need?

I'm not making fun of these women at all but it fascinates me that some-one's body will crave bubbles or sponges. I can understand dirt in the sense that maybe it has some sort of nutrient/mineral that the body might lack, but sponges? Really?
