Insomnia: It is very, very, very rare & is characterized by progressive insomnia associated w/ extreme changes in personality & behavior eventually resulting in dementia & death, usually over the course of a year or two. It's related to mad cow disease & creutzfeldt jakob disease & is caused by accumulation of misfolded prion proteins in the brain. You don't have it.
