I've had various forms of insomnia most of my life. If this could really be turned into a reliable technique or product for people to fall asleep, they would become rich. Recently, my bigger problem is I wake up in the middle of the night and can't fall back asleep easily.
Insomnia effects so many people and it increases to effect more people over time. I have found that reducing overall internet and computer usage has greatly increased my ability to fall asleep.
