The Insomniac

""I detest sleep. I've got better things to do. Besides, I find it frightening -- to awaken and be unsure of everything you remember about life not being just part of a dream. Waking means I've slept, and sleep dissolves what certainty I have left.""

- Johnny, Johnny the Homicidal Maniac

A common way to convey that a character is either really strange or has either paranoid or schizophrenic tendencies (or both) is to make them an insomniac. Whether only during times of great stress or as a chronic disorder (obviously a case of Truth in Television) expect these characters to be cranky, moody, mistrusting and sometimes even violent.

Expect lots of Eye Tropes.

In fiction, four types can be observed:


 * A. The Goofy Insomniac: Usually used as a comedy device. The character in question goes without sleep for a number of days (as these characters are often only temporary insomniacs) and react comically out-of-character for the duration of their sleep deprivation.
 * B. The Obsessive Insomniac: More likely to be a chronic insomniac. This character is so driven to catch or kill their nemesis that they forgo everything, including sleep. Typically, their sheer determination, rigid mindset and complete disregard for their bodies' needs actually make them more capable, making this a common Disability Superpower. See also Triple Shifter. May result in a Heroic RROD.
 * C. The Realistic Insomniac: Often used in more serious works, where the disorder is neither funny nor makes the character any better at what they do. Often the delusional/hallucinogetic part of sleep deprivation is played up, sometimes in conjunction with Tomato in the Mirror surprises for the viewer.
 * D. The Superpowered Insomniac: Part of the character's power set is the ability to go without sleep—either for long periods of time or for good. The Undead nearly always fit into this category as a general rule, usually pairing it with Perpetual Motion Monster.

See also Bad Dreams. Waking up from one may cause a sleepless night; waking up from one many, many, many nights may lead to this in its milder forms, since the character gets some sleep. Characters for whom not sleeping is normal are The Sleepless, though it can overlap with this trope, particularly the obsessives of Type B.

The webcomic No Rest for The Wicked can be found by following that link.

Anime and Manga

 * L from Death Note gets far less sleep than should be healthy for him - though like his eating habits, it doesn't seem to have any negative effect. His insomnia is arguably one of the reasons why he's the best three detectives in the world at the same time.
 * Possibly as a callback to the above, in Bakuman｡ (by the same scenarist/artist duo) Mashiro often foregoes sleep for days on end in order to work. It's mostly B-type, though it is also often Played for Laughs (his face gets zombie-like) and shown to have realistic consequences on his health.
 * Gaara from Naruto, who remains awake to prevent a forcible takeover by the monster inside him. He seems to spend most of the time a normal person would spend sleeping just standing still, likely to get physical rest (and possibly trying some form of meditation to make up for the loss of mental rest).
 * Keiichi states a few times that this is becoming the case in Onikakushi-hen of Higurashi no Naku Koro ni. Hey, you'd become an insomniac too, if you thought your friends were trying to stalk and kill you..
 * It's implied that
 * Hayate sleeps less than an hour a night: He goes to sleep at 4 AM, and is dressed and preparing breakfast at 5 AM. He's apparently been like this since he was six.
 * Kaoru of Virgin Love, thanks to being perpetually haunted by Bad Dreams of his childhood. He discovers being in a stable relationship combats this.
 * Beet in Beet the Vandel Buster stays awake for 72 hours, then sleeps for 24. Since the series is on indefinite Series Hiatus due to the illustrator being ill for five years and counting, and the writer's inability to find a replacement, we may never know why his sleep pattern is so unique.
 * Syrus/Sho is Type B for a while in "Yu-Gi-Oh GX" when he's obsessed with finding the lost Jaden. It makes him a bit more impulsive he does suffer a Heroic RROD by the end.
 * Casca from Berserk shows signs of sleep deprivation after the Eclipse, another realistic after effect of those who were a victim of  like she.

During a time skip, however, she meets up with an armada of a Proud Warrior Race whose home planet is permanently dark, who give her Training from Hell that turns her unreliable visions and narcolepsy into pinpoint tactical precognition and not sleeping ever again.
 * Irredeemable: Max Damage is one of these out of necessity: the effectiveness of his powers are directly proportional to how long he's been awake. Unfortunately, he isn't immune to the effects of sleep deprivation, and is depicted as a Type C.
 * The titular Mister X is a Mad Architect who takes a variety of homemade drugs to stay awake for months on end so he can attempt to fix the 'psychetecture' of a city he may or may not have designed. The city itself may also cause sleep disorders in its inhabitants.

His powers let him stay awake for weeks or months at a time, but then he hibernates, and wakes up in a new form with new powers.

So, when he starts getting tired, he turns to drugs, leading to Type C behavior.

Real Life
--
 * Peter Tripp, a disc jockey who went for 8 days without sleep in 1959 as part of a wake-a-thon stunt. He suffered heavily from hallucinations during the experience and its been suggested that he was never quite the same after the experience, which might hint at permanent damage. A trippy experience. According to the Wikipedia article, for the last 66 hours of that marathon the observing scientists and doctors gave him drugs to help him stay awake! Yeesh, first do no harm? Were they away that day?
 * Possibly Michael Jackson; his need for stronger anesthetics just to sleep may have caused his death. Ironically, the powerful drug that he was attempting to use is a poor choice as it only works for minutes at a time.
 * As mentioned above, Fatal Familial Insomnia is a genetic disease which causes the breakdown of the mechanisms in the brain which allow sleep (meaning that falling asleep becomes entirely impossible), resulting in insanity followed shortly by death. It is a dominant and autosomal (meaning it affects men and women equally) trait, a person who possesses the trait has a 50% chance of passing it to their child, and it inevitably affects anyone who possesses the trait. There is currently no treatment or cure. Thankfully, it is incredibly rare, only affecting 50 known families worldwide. To make matters worse, it doesn't manifest until the patient is anywhere from 30 to 60 (average about 50), which gives the future patient time to have children before finding out that oops, they inherited that gene (and in women, childbirth can trigger it).
 * Part of what causes meth addicts to be so paranoid is the days or weeks without sleep, due to being on such strong stimulants.
 * And then there is those who suffer from Hypnophobia.
 * Happens to many participants of NaNoWriMo.
 * Full International Baccalaureate students don't usually sleep more than two hours on average until the weekend or long breaks. Eventually, some of them become accustomed to it.
 * In some cases, people with post-traumatic stress disorder suffer from insomnia as part and parcel of the disease, especially in people with this disease who have nightmares about their traumatic experience. Alternatively, a person with PTSD could be lying down trying to sleep and then, BAM! they relive their traumatic experience and it takes a while for them to recover from this so they can sleep.
 * There are countless examples of artists who have had or do have sleeping problems, Emilie Autumn, Michael Jackson and Owl City are a few examples.
