I've noticed a few things that I am more sensitive to, but it's definitely not everything. My dog's breath smells totally different to me now. I thought maybe something was wrong with her, but my husband said it smells normal to him. One day last week he set the timer on the coffee pot the night before, so when we woke up we'd have our coffee already made (we used to do this most nights, but lately I haven't had an appetite for coffee), and when we woke up in the morning I asked him if he set it. I'd never smelled it before from upstairs, but I could instantly tell when I woke up that there was coffee made.
