I had signs of insomnia in the last couple of years. Tried all the usual techniques, and I realized those just do not work for one simple reason - that the moment i do not fall asleep, i become frustrated. And that frustration in turn makes sleeping much harder.

So, I tried doing the exact opposite, and my sleep has been tremendously better since.

Essentially, i force myself to keep my eyes open. When I catch myself falling asleep, I actually force myself to keep them often again. Before i know it, it is morning.

It sounds counter-intuitive, but all my insomnia problems are over, including on a plane. Would love to know if it works for others, or if it is just a silly thing that works for only me.
