Here's why a good night's sleep is so important ... and how to get it

FOR two months I only slept three or four hours a night. That was 10 years ago and I’d just landed a job I had really wanted. A week of sleepless nights because of new-job-nerves might have been understandable, even normal, but this morphed into insomnia.
I tried everything — lavender on the pillow, relaxation tapes, caffeine reduction, and I shunned TV and stimulating mental activities in the run-up to bed-time. Nothing worked — most nights, I saw the clock strike 2am, 3am, 4am. I was caught in an endless loop of worrying that I couldn’t sleep — and then not being able to sleep.
