Whenvever I am near some aroma, perfume or any other smell, my brain becomes numb. It can be cooking smell, perfume, cologne. As a result of this I can't use any cologne... I try not to use any aromatic product but main problem arises when I am going for a exam. If the person who is sitting beside me in a bus has put on some strong smelling oil or perfume, or If in the examination hall, the person next to me has put on strong smell ,my mind becomes numb. What to do to get rid of this problem?
