I've tried everything from alcohol, warm baths, lavender oil, reading, counting, exhausting myself during the day, no caffeine for a couple of hours before bedtime, getting up earlier and can state that most of them don't work (for me.) I was actually the (tired
) face of the Sleep Well campaign last year. I am currently trying a blue light box which is supposed to induce sleep. It flashes a subtle blue light which gets lighter and dimmer and mimics the heartbeat. Eight nights out of ten I don't find it particularly effective but sometimes I think it works.
