I've always loved the petrol smell too.

But my wierd ones are smells more than foods.

I have a dettol bath and use half a bottle each bath.
Eat about 9-12 ice trays full of ice (obviously)
Spray (more like drown ) myself in ICO impulse I go through a can in 2 night, I inhale the fumes and smell, till it's gone, then drown myself again.

Scary thing is though Im doing it now and Im not even pregnant, all of the above Im doing! Now that's weird!! #-o
