I was just going to add this too Danielle. Last night, my daughter was cooking some beef steaks and I kept saying, "What is that smell?" "Do I smell sour cream?" She says, "I made that mistake once mom, never again!" Yet, I couldn't get this terrible scent out of my head. I went outside and watered my flowers, talked on my cellphone to someone and when I came back in, it hit me--it was just the odor of cooked beef! I no longer can eat beef, no red meat, for that matter and must be I can't smell it either. Was weird!
