Insomnia is the inability to sleep regularly, and it can be caused by many different things. There are insomnia quotes that cover stress, poor eating habits, unhealthy sleep patterns, and even diseases and disorders which could cause a lack of sleep in your situation. If you are a sloth all day and you get little exercise then this can interfere with sleep, because your body may not be truly tired and you could toss and turn all night long. Lying in bed for hours on end trying to get to sleep can be self defeating, and you may start to dread going to bed at night. There are medications which can help with insomnia but these should never be taken on a long term basis because they can be habit forming or contribute to insomnia over time.
