For the past week I smell cigarette smoke when no one else does. We do not smoke, no one has ever smoked in our home or office. Only I smell this and it goes on for hours. I tried taking a shower but it did not help. The smell is definately in my nose as it follows me no matter where I go. (I left the house & got in the car, went to a store, etc.)

Already Tried:
