I think we tried it once last winter and it worked great one night and not so much the other night, so not sure.
I do know DH totally loves this stuff, and his family swears by it for a variety of things as part of Chinese medicine. I will admit I can't breathe at night from allergies and put a little under each nostril before I drift off, and it is the only way I can breathe.
We each have a tub of it on our nightstand (well, not the girls...they hate it since it makes their eyes water).

As the saying goes, when a door slams shut in one place a window opens somewhere else. After staring at the door for many years, it finally occured to me to go look for the open window. I discovered I like sunlight and warmth much more than peeling old doors anyway, so I climbed out the window and reveled in my discovery. I will never sit behind a closed door again, no matter how comfortable my chair becomes. Me
Mel, I'm glad you found your own open window and stepped through it.
