How sensitive is your sense of smell?

Because I have fibromyalgia, all of my senses are heightened. One doctor prefers to call the illness central sensitization or central sensitivity syndrome. My sense of smell is to a point where I wish I didn't have one at all. I cannot stand smelling stuff all the time. I smell stuff that no one else smells, stuff that may not even be there. You don't have to tell me my sense of smell is sensitive. I want to cut my nose off!
