I am 62 yrs. old, in menopause for years now. Within the past year I have experienced overpowering smells, and blackouts. The other day I found myself standing, unaware of how I got there, unaware of anything around me. Somehow I realized I was in the wrong place, turned around and walked to where I was supposed to be. These "blackouts" only last a few seconds, while my eyes are open I'm not "seeing" anything or hearing anything. I had three episodes of smelling a strong odor that morning, to the point that I had to hold my nose closed. For two or three days afterward I have a bad taste in my mouth and food doesn't taste right. Any ideas?
