For those who have tried everything, here are knowledgeable and surprising suggestions.
In contrast to practically every other aspect of life, effort in the area of sleep is not rewarded. Actually, it is formally sanctioned. The likelihood of success decreases with increased effort. This is so because, like respiration and digestion, sleep is a passive process. There is no way to control it, and nothing we do will make it happen. Sleep will come naturally if we can quit trying. But resisting the need to sleep is quite difficult, especially when you’re worn out and in need. “Stop reading articles on sleep,” the last item on the list, looks humorous. Other suggestions include “Give up attempting to sleep tonight, Breathe less, Have a late night, Wind up your wind-down process, Embrace being awake, Smile more.”
