Insomnia - Wake up and smell the coffee. Insomnia, as you probably know already, refers to a lack of sleep. Like most of these disabilities it's broken down into sub categories Ready for your pointless bedtime story on this? Then i'll begin. Once upon time there were 3 Kings who had great difficulty sleeping. The first King suffered from Transient insomnia which only lasted for a couple of days. The second King had Short-term insomnia he was pretty miserable as he couldn't sleep for more then a few days, but he managed to go to beddy-byes within three weeks. The Third King however was a right short-tempered bastard as his sleeping condition was Chronic insomnia which lasted three or more weeks, he had mental health problems which led to alcohol abuse and miss use of medicines which he tried to conquer his problem. In the end they all lived happily ever after enjoying their required 7 - 9 hours sleep which deteriorated to 6 hours when they handed down their crowns after their 70th Birthday. Apart from the third King who sadly asleep at the wheel and had a fatal car crash!
