Oh yeah, finally knew what caused insomnia

What causes it?
Typically, there is no single cause for insomnia but a number of factors are known to contribute.
Lifestyle - eating late at night, jet lag, hunger, alcohol, caffeine, stimulant drugs, including nicotine.
Environment – noise (eg partner snoring), uncomfortable bed or bedroom.
Physical health problems – sleep apnoea (abnormal breathing while asleep), asthma, tinnitus, pain, prostate problems that mean frequent trips to the toilet at night, and indigestion.
Psychological – including stress or grief.
Mental health problem such as depression or anxiety.
Medication – eg certain tablets for asthma and treatments for nasal congestion, vertigo and depression.

Sleep
The exact function of sleep is not fully understood, but the effects of lack of sleep suggest that its main function is to rest and repair the body. There are also psychological benefits. One phase of sleep is called rapid eye movement (REM) because the sleeper's eyes can be seen to move rapidly behind the lids. This is thought to be the time when dreams occur. People who don't sleep for long enough or who sleep very lightly, become deprived of REM sleep. They can become irritable and anxious and, in extreme sleep deprivation may even have hallucinations.

Also something called the pineal gland produces melatonin, which is said to restore sleep cycles and combat jet lag.. produced by the pineal gland. Maybe mine is cranking up for the day...
