I came across a technique to assist in falling asleep in seconds. I cannot take credit for this and I wish I could identify the individuals who discovered it, but for me, it works. It is a very simple techniques that only takes seconds to perform.
1. With the mouth closed, inhale through the nostrils to a count of four.
2. Still holding the breath, count to seven.
3. Open the mouth and exhale to a count of eight.
4. Repeat four times.
Normally, I do not get to the fourth time. I start yawning on the third time and lose focus or concentration during the fourth attempt.
