I too have gone from being the worlds most olfactory sensitive person to craving the smell of cleansers, strong essential oils (like sage) and menthol, and I am not sure why. I am cleaning my house top to bottom so that I can smell the cleanser. I almost killed my mom with Pine Sol, as she has heart conditions and asthma. Now, I use Fabulosa all through the house and even put some on a kleenex so that I could smell it in private all day long. I am thinking this is a mineral deficiency, especially Zinc.I have in the past been the sensitive nose among all, now, all I want is strong odors of cleansers. I know it is weird, but i am going through this too. So, I hope that we find an answer soon as this is very disturbing to me. :eek:
