Its like you were telling me about my own past.... my odor problem first set in when i used to smoke pot and used to get paranoid. I stopped smoking pot shortly after as I felt I was getting too paranoid about the whole odor problem though after I stopped smoking the paranoia stayed as did the smell.
Fast forward several years to now... i still don't do drugs, though the paranoia now is still there of smelling all the time. Im going to read up on this further.
