 I don't know how to work for Relief Factor, but I don't know of another product. Z-Factor. Z as in zzz, as in sleeping. And it's one of the arenas where I know how lucky I am in life because I fall asleep immediately and I stay asleep the whole night. It's been true my whole life. There are so many of you for whom that is not true. My heart goes out to you. That's a curse.
