For years I loved Chanel No. 19. Then I moved away from it and tried other scents for a while. Just a few years ago I got a new No. 19 EDP and was shocked at how much I disliked it, especially when I wore it. It wasn't just "eh" - it was an active dislike.
I was inspired by your post, milla, to give it a whirl a couple of days ago and guess what? I love it again. It smells exactly as I remember it from all those years ago too.
All I can figure is that menopause, medications, and/or stress over the past years affected the way the fragrance smelled on me and/or my sense of smell.
I, too, love to use it exactly as you do, milla. Bedtime and sweaters - not sure why those 2 very different times and places are so appealing.
Now I'm looking forward to trying some other scents that I used to love but had given up on, including No. 5 for evening.
