Craving gas/exhaust/tar smells

So over the last 3 months i have been craving really badly the smell of exhaust, gas, kerosine, tar, etc. I have never been like this before (i always like the smells but never craved them).  I have been very hormonal and have been brusing easy my arms are constantly brused for no reason ( i am not sure if this is related but i thought i would mention it).  I also had really bad headaches for a 2 week stretch, but they went away. Does anyone have any clues as to what all this could mean? or am i crazy?

You need to be seen by your primary care physician.  Many times, odd cravings or smells can be symptoms of serious underlying disorders.

Especially with your history of bruising and a 2 week long cluster of headaches.

I also found myself with a strong "strange" craving to inhale gasoline.  I was  in my late 50's when it started, and do not drink alcohol, or do drugs of any kind.  I found myself looking around the house and sniffing different things, but found no satisfaction to my urges until I picked up that gasoline can in the garage.  That was what I was craving!!!  I have no idea why!  This went on as a daily routine for about 8 months.  I would lose track of time with my face hovering over that gas can for hours.  My husband would leave for work, and I would go to the garage and begin smelling the gas.  The next thing I was aware of was that it was afternoon!  I lost the whole day in a sort of dream state.  It all seemed so real, except the time I was a cartoon.  How strange that was.  Not only was I satisfying my urge, but this was entertaining.  I then realized that I was probably doing something very dangerous to my health.  I prayed for strength, and God helped me to overcome.  It has been several years now since I have inhaled gasoline.  Lately however, the memory of it is creeping back into my mind.  I must stop it before it starts again, and with God's help, and my determination, I'll succeed.  I hope this may have helped someone who has experienced this strange problem.  I still don't know the cause of the sudden urge to inhale gasoline.  I wish I did, but I'm to ashamed to ask my Dr.  I believe it has something to do with some deficiency in vitamins or other nutrients.  Thanks for the opportunity to "get this off my chest"!  Oh yes, by the way, a friend told me one day, during my inhaling days, that although she knows I am a very clean person, that I am beginning to smell odd.  I suppose the gas had penetrated my skin, hair, etc.  It is all so confusing to me!!!!!!
