Absolute cure for insomnia:
First you must eliminate most of the stimulants which you might be using routinely, such as caffeine, alcohol, and nicotein, from your daily routine (only exception being morning coffee).
If you smoke, reduce your daily intake.
1. Get a copy of an English translation of What Is to Be Done? by Vlademir Lenin, from a used book store.
2. Then take a hot bath or long shower.
3. Get in bed, unplug all noisemakers such as telephones, cell phones, radios, TV.
4. Then start reading that book.
I guarantee you will fall asleep within 30 minutes.
There are no safe pharmaceutical sleep drugs.
None.
Use of any of them for more than a few days will produce coordination problems, memory loss, and dependency ranging from "habit-forming" to outright addiction.
If combined with alcohol or other drugs they can produce coma and/or death.
