I spend a lot of time thinking about sleep. It's my job. And beyond that, I'm a true believer: I went from not sleeping very well and dismissing it with an "I guess it's just the way I am, and I'm not really interested in taking sleeping pills" to appreciating the delicious feeling of waking well-rested. The first time it happened was a revelation. I felt AH-MAZING, and immediately became jealous of my husband, who apparently wakes up feeling that great all the time.
